What american slang words do foreigners find funny?

Question

I'm curious to know what American slang words or phrases foreigners find funny. I have a friend that went to Australia and people laughed when he said:

"you that is hella mad crazy" when he was saying that he liked something. And everyone laughed and said they thought it was funny. So I'm curious what people all over the world think are funny American slang words.

Answer 1

When my step-son went to the States for 12 months he played football for a while. Before one game the coach told the team that he wanted them to go out and kick the other's teams fannies. The previous post will give you an idea of how funny this is to non-Americans. (My step -son thought they must have been going to play a female team, and that the coach was rather brutal).
