The act of placing a cigar in a persons ass and lighting the end that is sticking out. The person is instructed to use thier anal muscles to take a draw on the cigar. When it is done the other person removes the cigar and places thier mouth over the other one asshole and the person blows the smoke in that person mouth.
My girlfriend after we had anal sex placed a cigar in her ass and gave me an Anal Shotgun
The act of shotgunning a beer by poking a hole in the bottom of the can rather than the side of the can and chugging the beer as fast as possible.
We anal shotgunned way to many beers last night.
