When Lisa McGee’s masterpiece Derry Girls arrived on international screens via Netflix, viewers outside the United Kingdom and Ireland were treated to two simultaneous revelations: first, that 1990s Northern Ireland during The Troubles could host one of the most riotously funny teen comedies ever written; and second, that they urgently needed subtitles, an Irish-English dictionary, and a pause button.

Set in Derry in the mid-1990s, the series follows Erin Quinn (Saoirse-Monica Jackson), her eccentric cousin Orla (Louisa Harland), neurotic Clare (Nicola Coughlan), swaggering Michelle (Jamie-Lee O’Donnell), and the perpetually bewildered “wee English fella” James (Dylan Llewellyn).

Much like the hyper-specific regional dialects we decoded in Australian slang from Colin from Accounts, the posh aristocratic swearing in our guide to The Gentlemen, and the soccer banter analyzed across British slang words in Ted Lasso, Derry Girls turns regional Northern Irish dialect into an Olympic sport of rapid-fire linguistic comedy.

For international fans re-watching the series or quoting it with friends, here is the definitive, ranked guide to the 12 funniest Derry Girls slang terms, insults, and lines decoded for the rest of the world.

1. “Catch Yourself On”

  • In the Show: Spoken dozens of times, usually by Michelle or Erin’s mother Mary whenever someone has an inflated sense of self-importance or an unhinged romantic fantasy.
  • Literal Translation: “Get a grip on reality” / “Stop talking nonsense.”
  • The Cultural Context: In Derry, delusion is not tolerated for more than four seconds. If you express high-minded literary ambitions (like Erin claiming she is a tragic poet) or propose an insane scheme (like sneaking across the border in the trunk of a car), you will immediately be told to catch yourself on.
  • The Comedic Power: It is the sharpest, quickest comedic needle in Irish vernacular. It instantly punctures self-seriousness before a character can even finish their sentence.

2. “Mother of God”

  • In the Show: Delivered with theatrical exhaustion by Ma Mary (Tara Lynne O’Neill), Aunt Sarah, or Granda Joe (Ian McElhinney) whenever a fresh domestic catastrophe strikes.
  • Literal Translation: A traditional Catholic invocation of the Virgin Mary, transformed through Irish maternal delivery into: “I cannot believe the universe is doing this to me right now.”
  • The Comedic Context: The brilliance lies in the pacing. Whether the family has encountered armed military checkpoints, burnt the Sunday roast, or discovered that Aunt Sarah lost her eyebrows in a makeup mishap, “Mother of God” is treated with the exact same apocalyptic weight.

3. “Wee”

  • In the Show: “Wee English fella,” “wee bag of chips,” “wee chat,” “wee massive problem.”
  • Literal Translation: Literally means “small,” but in Northern Ireland it is applied as a conversational punctuation mark to literally anything.
  • The Dialect Trap: A “wee person” might be six-foot-four. A “wee delay” might take four hours. In one of the show’s best running gags, James is perpetually dubbed the “wee English fella”—a diminutive that strips him of any masculine swagger while cementing his place as an honorary Derry Girl.

The Rule of the 'Wee' Diminutive

In Ulster Scots and Northern Irish dialect, 'wee' does not measure physical size. It softens social awkwardness, creates conversational intimacy, and makes potentially aggressive statements sound harmless. Telling someone you want a 'wee word' is Derry code for an incoming lecture.

4. “Eejit” (and “Pure Eejit”)

  • In the Show: Michelle and Gerry’s go-to character assassination tool for friends, family, and authority figures.
  • Literal Translation: Idiot / Fool.
  • The Hierarchy:
  • An Eejit: An ordinary fool making a regular mistake.
  • A Pure Eejit: Someone whose foolishness has reached astronomical, almost impressive heights.
  • Why It’s Funny: Unlike the harsh American “idiot,” eejit carries a musical, bouncy rhythm that can express profound frustration, protective affection, or absolute disbelief depending on whether the vowel is dragged out.

5. “Ride”

  • In the Show: Michelle constantly scouting boys at parties, church halls, and school dances: “He is an absolute ride, Clare!”
  • Literal Translation: An extremely attractive, desirable person.
  • The American Trap: To North American ears, “ride” refers to an automobile or transportation. Hearing four high-school girls aggressively debate whether the new French exchange student is “a ride or not” causes immediate confusion for first-time viewers.
  • The Comedic Context: Michelle’s obsession with finding “rides” drives half of the series’ plots, contrasting with her actual, disastrously clumsy attempts at romance.

6. “Craic” (Good Craic vs. No Craic)

  • In the Show: Used in every episode to gauge whether an event, person, or evening has any redeeming entertainment value.
  • Literal Translation: Fun, news, gossip, conversation, or good times (pronounced crack).
  • The Derry Grading Scale:
  • Good craic: A lively, hilarious night.
  • Mighty craic: An unforgettable party.
  • No craic: Boring, lifeless, and unworthy of respect.
  • Cultural Lore: Nothing in Derry culture is worse than being labeled “no craic.” If you ruin a plan by having common sense, Michelle will immediately accuse you of being a buzzkill who hates joy.

7. “Wain” (Pronounced ‘Wayne’)

  • In the Show: Used by adults to refer to the teenagers: “Look at the state of these wains!”
  • Literal Translation: Child or kid (derived from the Scottish/Irish contraction of “wee one”).
  • The Comedic Context: Even as Erin, Clare, Orla, and Michelle believe they are worldly, sophisticated young women navigating romance and politics, the town elders continuously refer to them as “clueless wains,” highlighting the gap between their teenage egos and reality.

8. “Bake” (Pronounced ‘Beak’)

  • In the Show: “Shut your bake!” or “Look at the bake on her.”
  • Literal Translation: Face or mouth.
  • The Comedic Context: It is an aggressive, wonderfully visceral Derry insult used to tell someone to stop talking or to criticize an obnoxious facial expression. When Sister Michael looks at the girls with contempt, having a “sour bake” is the greatest offense imaginable.

9. “Slagging”

  • In the Show: The merciless teasing the girls inflict on James every time he attempts to use British slang or complain about Derry food.
  • Literal Translation: Roasting, making fun of someone, or banter.
  • Why It Matters: In Irish culture, slagging is the ultimate love language. If people are polite and distant with you, they don’t trust you; if they relentlessly mock your coat, your haircut, and your tea preferences, you are officially family.

10. “Melt” & “Doing My Head In”

  • In the Show: Clare screaming in panic: “She is an absolute melt, Erin!”
  • Literal Translation: An irritating, exhausting person who melts your brain with annoyance.
  • The Comedic Context: Clare’s hyper-anxious personality makes her particularly susceptible to “melting.” When someone talks too slowly or a teacher assigns extra homework, the feeling of mental disintegration is captured perfectly by the term.

11. Sister Michael’s Greatest Roast: The Pastoral Guidance Masterclass

  • The Line: “If anyone is feeling anxious, worried, or in need of guidance… please, don’t come crying to me.” — Sister Michael (Siobhan McSweeney)
  • The Context: Delivering school assembly announcements at Our Lady Immaculate College with a deadpan stare that could freeze lava.
  • Why It’s Legendary: Sister Michael subverts the warm, maternal Catholic nun archetype into an unbothered, judo-practicing nihilist whose only desire in life is to read The Exorcist in peace and drive away from school on her scooter.
Iconic Character Moment ★ Sister Michael Genius Season 1, Episode 1 • Written by Lisa McGee

The Priest's Monologue: When a handsome young priest visits the school and all the girls swoon, Sister Michael leans over with pure deadpan brilliance: "Unfortunately, Father Peter, looking like a pop star does not excuse you from being an absolute bore."

12. Uncle Colm’s Legendary Hostage Monologue

  • The Line: “So anyway, there I was, tied to the radiator, and I said to the fella with the balaclava, I says: ‘Is that wool or synthetic? Because my sister-in-law had a synthetic jumper once and it gave her a rash on the clavicle…’” — Uncle Colm (Gerard McCarthy)
  • The Context: Recounting an armed bank robbery with excruciating, mundane detail while everyone in the room prays for sweet release.
  • Why It’s Legendary: Uncle Colm is Derry’s resident energy vampire—predating Colin Robinson from our analysis of the 15 best What We Do in the Shadows quotes! He is so terrifyingly boring that even armed paramilitary fighters eventually untie him just to make him stop talking about his lawnmower.
