Butt Hummer 

Sexual act; during anal sex (typically best between men) at the point of climax, the recipient of the load blasts a forceful, monstrous anal queef vibrating the schlong as it makes the deposit.

I was slamming this dude's ass last night and he gave me a crazy dope butt hummer. I was in heaven until I realized he back blasted me with shit streaked sperm.

Butt Hammered 

The act of being extremely intoxicated, far worse than butt trashed. An entirely new dimension of drunk. Enough said.

Sarah, you were butt hammered last night.

butt hammer

A ransack of one's asshole so extremely deep and hard that bum crumbs and ass debris are scattered about the area. After a butt hammer one's asshole can only be described as ass dough.

1st guy:Dude, why is your girlfriend limping?
2nd guy:After a butt hammer no one walks straight

Immune to the laws of physics and incapable of independent activity, the butthumper finds your rear bumper on an open stretch of highway, and stays there. The asshole may be using you as a shield against radar, or as a fuel-mileage aid, but usually he/she is talking on the phone and relying on you to scan the road for them.

Ten lanes of superhighway to drive on and this jerk has to tailgate me. What a butthumper.
