1: The front seat next to the driver in a vehicle, normally called out loud to get the seat.

2: A gun that fires a shell which bursts into a lot of buckshot pellets that spread very quickly. The damage of all these pellets put together is enormous, making the gun one of the strongest ever at close range (from point blank to about four meters), but because of the fast spread nearly useless at long range.
I'm driving.

The word you yell when you are about to let loose a serious case of projectile diarrhea. Usually into the toilet or into the back of the toilet bowl (sometimes on the seat or completely out of the toilet as a whole).

Sometimes said like this: SHOT!... Guun!!!
(a quick "SHOT!" followed by a 1.5 second pause, then "Guun!!!")
Two Guys in a public restroom:

Pooper2: SHOTGUN!!! (In Tandem with projectile Diarrhea.)
