Craic
Craic is the social spark of the whole thing: the chat, the laughs, the gossip, the messing, the buzz in the room. If something was good craic, it was lively and worth showing up for. If someone's great craic, they're good company. What's the craic? means what's going on, and no craic means the vibe's gone a bit dead.
Culchie
A culchie is someone from rural Ireland, especially from outside Dublin. In Dublin mouths it can be a light dig at country people. Said by rural people themselves, it often flips into pride. It's one of those labels that can either wink or puff its chest out, depending on who's firing it.
Eejit
Eejit is a soft, affectionate way of calling someone an idiot after they've done something daft, clumsy, or wildly obvious. It's usually more warm ribbing than a proper insult, the sort of word you'd throw at a mate, your brother, or yourself when your brain's gone out for a smoke.
Gas
In Irish English, gas means something or someone is properly hilarious, mad entertaining, or just great value. You'd say that's gas when a story, mishap, or person has everyone creased. It's close to saying something's great craic, but gas leans more toward the laugh itself and that cheeky burst of comedy.
Grand
A very Irish catch-all for fine, okay, sorted enough, or leave it there. It often runs on understatement. Someone can say grand when things are actually lovely, slightly cursed, or hanging together by a thread. The tone does the heavy lifting, so grand might mean real comfort, weary survival, or a polite way to stop the fuss.
Sound
Sound is a very Irish way to say someoneโs decent, reliable, and just good people. If a person is sound, theyโre the kind youโd trust, have a laugh with, or count on not to mess you about. It also works as a quick reply for alright, grand, nice one, or no bother when youโre agreeing to something.
Deadly
Means brilliant, class, seriously good, even though it sounds like a warning label. In Irish chat youโll call a film, a night out, or even someoneโs new jacket deadly when itโs spot on. Itโs an easy, high-grade compliment, usually said deadpan like itโs no big deal, which somehow makes it even better.
