LOL, this list is hilarious!!
One of my best friends is the backfromgym guy/holder/farting machine. He's immensely strong and likes to try to pin me until I run out of gas. he has about 60lbs on me so getting pinned by him sucks
There's a pretty damn good purple belt at my gym who is the pretzel/latecomer. Shows up at the end of class just to roll, and has superhuman flexibility. His guard is EXTREMELY hard to pass
I could go on and on and on, I know almost all these guys!!
as for me, I'm probably some combination of the pretzel and the risk taker. occasionally I'll be the all knees and elbows guy. against some opponents I sometimes feel like the mailman, which kinda sucks and is something I'm working on
