A friend of mine and I have a running joke of a picture we saw, which we gave the caption "What do you want?" said in a funny sounding low voice. Basically, at first it was used when something awesome happened. For e.g. *We are playing basketball, I do some ridiculous behind the back shot and it goes in* "WHAT DO YOU WANT?" *We both laugh*
Only, it has become more of a regular greeting and saying for me, however, I do try to keep it with close buddies who already know I'm a weirdo as to not bewilder other people.
