What's In A Name?

I have picked up many names over the years, most are not really flattering, but what the hell, I suppose they are terms of endearment. Some of the better ones are Dino (and no not the purple dinosaur from the Flinstones), Big Daddy, Jackass, The Professor (my personal favorite), Gibby, and Mr. Slut (I really do not think that one will catch on). Some of the nicknames are obvious, some of them I have earned, and others I do not know what they are talking about. On the one hand I could say I made enough of an impression for the people to give me a term of endearment. On the other hand, I could say I have made a bad enough of an impression for them to give me a nickname. Either way, they remember who I am.
