(Shotgunning) Shotgunning a beer is the simple act of consuming a beer at a high rate of speed.
Shotgunnin a beer is easy when following these steps:

1) Hold a beer can in a horizontal position with the bottom tilted up just a bit. Poke a hole on the side near the bottom where you would see an air bubble if the can were clear. Poke this hole with a screwdriver, knife or a Shotgun Key.

2) Place your mouth over the hole while lifting it to an upright position.

3) After you have reached an upright position, pull the tab at the top of the can and consume the beer as fast as possible.

Shotgunning a beer is easy when you follow these directions!

A sexual act that involves a man cumming into another partner's mouth who has a gauged labret piercing. The partner with the piercing then yells "shotgun" and ejects the fluid at the man through the labret.

May also evolve into snowballing.

Thursday night was nookie night in my household, and I could tell it was my turn to return the favor. I grabbed my wife by the mouth and began shotgunning her like a champ.

When used in the context of seating in cars, "shotgun" means the passenger seat, so called because in police cars, the unit's mandatory shotgun used to be holstered in the passenger seat.
