In multiplayer FPS games, to repeatedly crouch on or "hump" the dead body of the person you just killed. Is pretty much pointless, but fun if you want to piss off the other guy.

While playing HALO multiplayer, after you kill a member of the other team, proceed to stand over the corpse and click the duck button multiple times. To others it appears that you are humping the corpse which will piss of the person you corpse humped.

In an online FPS game, to stand over the warm corpse of your opponent and repeately squat up and down in a display of dominance. This activity is usually accompanied by screaming something such as "You are owned, biach! How do you like that shit, fucker! Huh! Huh!" Ideally, this childish display of bravado ends abruptly with a sniper shot to the humpers head.
"Mom, you're messin' me up! Now CaptainUnderpants is corpse humping me! Get me some fuckin' chocolate milk!"

Someone bobbing up and down a dead body in a FPS and screaming anything from the run of the mill “Oh I fuckin pwned you!” to more interesting, “But why is all the rum gone?? Cuz your sucking dez rocks!!” So have fun with it and taunt the hell out of the n00b you just pwned and let him know what you think of him as your Corpse Humping his lifeless body.
