Quinton 'Rampage' Jackson might be a past-his-prime professional MMA fighter. But he's still a professional MMA fighter. Why in the world would you want to mess with him at a club?

Jackson was caught on video by TMZ getting into a clubgoer's face out on a Hollywood street after he was told the David Bowie-looking dude grabbed Jackson's girlfriend's ass.

"Tell my girlfriend sorry and you ain't gonna do that sh*t no more -- or you about to go to the f***ing hospital," Jackson told the man.

The skinny blonde guy in question says something back to 'Rampage,' but you can't hear what it is. It clearly was not an apology.

"You think I'm lying?" Jackson said. "He thinks I'm lying!"

Luckily, there was enough security and other people in between them to make sure 'Rampage' didn't land the kind of left hook that knocked out UFC legends Chuck Liddell and Wanderlei Silva.

Even if the guy didn't grope Jackson's girl, it doesn't matter. Just apologize and save yourself from potential bodily harm.

What, did he think 'Rampage' was above beating the crap out of him? This is the same guy who took California cops on a wild monster truck chase before being subdued at gunpoint in 2008.
