I can't say I learned all that much from my professors when I was in college, but I sure did learn a lot from my peers.  For instance I learned from one of my roommates, who hailed from Glasgow, that you could cuss someone out without suffering any consequences if you did so with a great accent. He'd insult people to their face and they'd just smile at him.  Granted, they probably didn't understand a word he was saying, but the words just sounded so much less vulgar when he said them.  I was reminded of this when I saw the picture on this post at Boing Boing. Seriously, can you imagine a US paper coming up with the headline that the Irish Daily Star did: USELESS GOBSHITES?

BTW, as a parent and an American citizen I can think of a million instances when this epithet would have come in handy.
