Chicken butt is the very strange name I used to call my friend to annoy the sh*t out of him. It worked, and EVERY DAY I get the same thing, I get my foot stepped on. The reason why I don't call him "chicken butt" any more is... he gets clucking angry. I now, for some reason, call him Jon. He hates that even more, amazingly. It's really funny to watch how he reacts to "Jon! Come over here!", and he comes over alright.
