The Keyon rumor thread made me think of this... my friends and I have always just randomly started coming up with nicknames for our players. Some are bland, others silly, some make very little sense, and all were yelled in a team-oriented stupor at some time publicly. Some of the things these guys did elicited some really common phrases from us too.
I bet you guys have some great material as well.
These aren't brilliant, but I'll share last year's to get started:
Stiemsma - Steamboat, "Greg, you stop it.... [to a friend] did you see that?!"
Paul - Pauly, "I can't believe he hit that!!!!!"
KG - "G", "OK, G, OK"
Rondo - "little Hondo," "Rondooooooooooo," "Dude... [wild use of profanities], he is 6'1, 180!!!! how is this possible?"
Ray - "He doesn't miss. He just never learned how to."
Pietrus - Peachies
Dooling - somehow became "Dools," then "Pooling," then "Poo poo"
Marquis - "avatar," "no, he's fine...he always looks high," "there's no way he doesn't have a shank right now"
Bradley - Nothing noteworthy here, but I did decide if I have a daughter to name her "Avery" (seriously)
Hollins/Sasha - not nice things at all
