guys the reason jays left biceps is more cut is simple
he jacks off with that hand ! think about it , jay is a hasbeen bro, who probably has a hard time getting his lil weasel hard from all the years of
steroid abuse. and other fine drugs. so he probably cant get his lil weasel up when some whore wants to fuck. thus he has to jack off more.
so using the weider "constant tension method" when jay punches his clown, he is keeping constant tension on that left bicep.
