Oh man I have a ton.
Stigmata - Got it freshmen year on the wrestling team because I would just randomly start bleeding from the wierdest areas.
Riddler - Dont really know how it started but it stuck for a while.
Ginsu - Use to do this wierd shit with my hands in a wrestling match.
Javino Latino - It stands for Albano Latin. This kid on our wrestling team was a foregin exchange student from Columbia and gave me the nick name.
Miami - I live in Mass, but Im from Miami. And I wear a hat from "The U" all the time so people up here just started to call me Miami.
Yea there is a lot more too.
