hump busted is catching two or more people in the process of busting each other's humps. Having sex gay straight or masturbating in a public place. Preferably while yelling "you've been hump busted!" Then running away.
I can hear these two guys gruntin in the men's room stall over there. I think I'm gonna bust they humps, throw open the door and let em know they've been humpbusted.

When having sex with a woman/man/other doggy-style, your penis slips out. It heads straight for Door Number 2 but gets jammedsideways in between the ass cheeks, thus resembling a broken table leg.
After his third slippery busted table leg, Bill was never the same.
