Nick names are gay as shit, but since I had no choice I embraced it, if u make up your own technically your a homo. 
Nope. If guys could give themselves their own nicknames everyone would be nicknamed The Duke. Fact of the matter is there can be only on The Duke and if they'd have decided to call him Panty Lips then that is what he'd have been stuck with. A nickname is like a birthmark you get what you get given to you. Thats all.
Rory McDonald seems to think so....
My roommate my freshman year in college nicknamed himself "Turbo Snoop".
NAMBLA Man - I chose my own nickname. Only because every fucking body wanted to call me some variation of "terminader" since my last name is Nader.
Did you ever get pressure for "Darth" Nader? Dude, when's the screen name bet over? Ouch.
