Listen up, it’s everything you need to know about that weird Irish invention - the craic.Thinkstock

Craic is the Irish word that most confuses outsiders. Yet it is a relatively simple concept. It is the atmosphere, fun, carry on surrounding a particular night out. ”How was the craic” is the first question uppermost in most young Irish minds after a weekend.

Her’s the encyclopedia definition:

"Craic" (/kræk/ KRACK), or "crack", is a term for news, gossip, fun, entertainment, and enjoyable conversation, particularly prominent in Ireland. It is often used with the definite article – the craic.

Here we rate the six kinds of craic (actually an English word which for some reason is in every Irish person’s soul).

5. The craic was ninety: The nirvana of craic, everything was amazing, incredible, everyone hooked up, the pints were great.

No one quite sure how the word ninety came into it--a famous Christy Moore song “The craic was ninety in the Isle of Man” maybe. 

And lastly!
