slam 

A massive shit, often smellier, messier, and more painful than normal. Yet, very rewarding once finished.

I just took a crazy slam. Anyone want a sandwich?

Slam. To Slam. Slammed.
1) To annihilate someone so badly in an argument to the point that they can't recover.
2) To beat someone down. (Usually involved in which the victim gets beat senseless.)

Bro 1: Bro! did you see Porter get slammed in that bar fight?!
Bro 2: Fuck yeah! I told Porter not to get in a fight with that dude.
Bro 1: And he did it anyways. What a Porter move.

See "Porter"
