DMX says he'll be jailed if promoters allow him to step in a boxing ring with George Zimmerman ... because he'd break every boxing rule in the book -- then piss on his face.
The 43-year old rapper tells TMZ ... he's throwing his name out as a potential opponent for George's upcoming celebrity boxing gig -- just like The Game -- and says he wants to do it for "every black person who has been done wrong in the system."
DMX adds, "I am going to beat the living f**k out him … I am breaking every rule in boxing to make sure I f**k him right up."
DMX says, "Once I am done with him, I am going to whip my d**k out and piss on him ... right in his muthaf**kin face."
He adds, "Zimmerman is a piece of s**t and that’s what he needs to drink."
We're guessing George won't take him up on the offer.
