Slam Dump 

The act of having a bowel movement that is so urgent and formidable that the individual grabs the toilet rim with two hands and vocalizes a sound similar to that of an NBA star who just dunked a basketball. Ie: "Ahhhhhhhhhgh"

Lebron James ain't got nothing on the two handed slam dump I just made in the teachers lounge toilet.

Slam dump 

The immediate release of poop as soon as you sit on the toilet after holding it in for a while or after eating too much. Just like a slam dunk, only done with the ass.

Having to take a shit real bad

I went to go eat with a friend the other day. When we go back to the dorm he scurried to the bathroom, taking small but quick steps. Seconds after he shut the door I heard him shout "slam dump!"

Grand Slam Dump 

A large shit that involves sweating and strainging so much that a change in wardrobe is necessary. Counting down from 10, start removing all your clothes. When all clothes are removed, release the load of shit from your anus and yell "Grand Slam". Then, if you are Spencer Meyer, continue to masturbate on the spot.

Dude, I just took a grand slam dump. It was awesome. Thats the second one this month!

Choke-slam dump-slap 

The act of defecating into a fellow-human's mouth such as to choke him with the size of the defecant. C.f. "shit eater."

"Yeah, he was pretty hot, but then he was all like I want to choke-slam dump-slap your purty-ass mouth."
