Where did the slang terms 'butt' originate from?

Question

Okay, I have a bit of spare time and not much to say (a rather dangerous combination), but here's something I've always wondered. Where did the term 'butt' originate, and is it used outside the United States? What about bum, backside, f***y and ***? Which do you use and think is more appropriate? Which cultures use which term more? Okay. I'm feeling adolescent today, but it's something to think about isn't it.

Answer 1

It's short for buttocks.

Answer 2

"Butt" comes from the word "buttocks."  

Answer 3

I'd assume from the actual term for one's backside, "buttocks".
