Slam Dunk 

On 20/20 w/ barbara walters there was a segment in which it depicted rest-home staff who would pick-up geriactric patients and roughly throw or "slam-dunk" them onto their beds. the "game" had an actual point system to it and ways for fellow co-workers to compete and score points as if it was an actual basketball game.

Hey Vinnie, check this out, I'ma slam dunk this old hag!!
BAHW!!

SLAM DUNK 

Derived from the British: SLAM, and the Alpha-Numeric: DUNK.
It has most recently been adopted by Devil May Cry Hero Dante.

It's most frequent use, though, is when nerdy 13 year old children believe it to be hilarious fun to exclaim SLAM DUNK whilst facing up the school bully. This, more often than not, leads to a swirlie.

Foolish Child 1: SLAM DUNK!
School Bully: Yo, Imma slam dunk your head into dat dere toilet. Fo shiz.

Dropping all of a nearly rolled spliff except for the rizla.

You have just returned from work and prepared a hard earned spliff. You've picked it up from the table. you've rolled it nearly all the way up when boomshanka! It's a SLAM DUNK!!! The contents are all over your lap and you are left hanging onto a rizla looking down at what you've just done.
