Mine is just a "Knickname" from some friends growing up. It was a substitute for "man" or "dude", as in when saying something like "what's up man?". Not sure how it came up, just mofos started saying it.
Guess I should have thought of something related to the Knicks, which would most certainly have involved John Starks (one of my all time faves). If I could change it without losing my post count, I probably would. Is that do-able Martin? Maybe something like "StarksOverMJ".
