When using the restroom, it is when a pocket of gas becomes trapped between two pieces of fecal matter, compressing the gas more and more until it ruptures sending the fecies harshly out of the sphinctor.

The act of inserting Diet Coke and Mentos into a partner's rectum, then checking them into a wall (hockey style). Followed by a heart-felt apology.

When having rough sex up the nasal cavity with a red-neck woman with HUGE nostrils and repeatedly bashing on the sinuses creating a hole in which the jizz can then penetrate the soft tissue of the brain, if executed correctly the bitch will not survive the blast.
When I was milking the donkey Gertrude asked what a Canadian sperm rocket was. I jumped up loaded it in her nostral and next thing i knew she was a dead as dinner. RIP Gertrude
