Again, why not give a definition of "craic"? This is what
I found:
what the heck does CRAIC mean? Its a Gaelic word that means the humor of the time, a bit of fun. Like one says "I am going out for a bit a craic" means going out for a great time, good humor and fun. Its a very Irish expression.

tsuwm's wwftd has a good definition. Why didn't he post it?
craic
[Irish] /crack/ the combined sensation of good conversation, good company, good times etc.: great fun


The only thing that could make the Irish politicians ban
smoking if that they have been show an abundance of evidence
that the care of the 7,000 who die from smoking each year
costs an extremely large amount of money, out of the public
treasury.
