UPDATE: Just to clarify, this is a true story, kind of a funny exchange in the car over a word used in a way that didn't make sense to someone whose first language is Arabic.
[Gooch and his Arab friend, Alex, are driving back from lunch. The Howard Stern show is on the radio and the words "douche bag" are heard]Alex: What is "douche bag"
Gooch: Well, literally, it's something that women use to clean themselves.
Alex: Why would you call someone that? Is he saying that the other guy is feminine?
Gooch: No, he's saying he's an idiot.
Alex: Wait... "douche" like the French word for "shower." Is he saying the other guy is not clean?
Gooch: No, "douche bag" is just a name people call each other.
[Two hours later, in the office, Alex hangs up the phone after talking to an operator about a credit card issue]Alex: That guy is a douche bag.
Gooch: See? You got it!
