What it means
Means something is hilarious or brilliantly entertaining. If a story, video, or person is gas, it has everyone laughing and the mood lifts straight away. Often used as quick praise, like That’s gas, and it sits in the same neighbourhood as good craic. Context matters, because you’re not talking petrol or farts, just pure comedic value. You’ll hear it after a blunder, a savage joke, or a mad bit of luck.
Usage examples
"Yer man tried to hop the kerb outside SuperValu, stalled it twice, and the whole queue was in stitches. Absolute gas, the craic was mighty."
"The best man’s speech was absolute gas, half the room was crying laughing before the starter even arrived."
"Your uncle is gas, he had the whole kitchen in stitches with that story about the runaway sheep."
Where it comes from
Hiberno-English picked this up from the old idea of laughing gas, the giddy nitrous high that left everyone in fits. Over time gas drifted from the chemistry to the comedy, so in Ireland calling something gas just means it had you doubled over, no canister required.
