The art of swallowing and lodging an object in your throat, and choking

To snap the neck of a dog, cat or other animal in a way that resembles unscrewing a bottlecap.

When a man or woman bites the head off of a penis during oral sex.

When a girl is licking your ass and you realize that you didn't wipe completely when taking a crap earlier in the day.

When you hot glue bottlecaps to your nipples, sexually, and seductively rub the outer ridges of said bottlecaps, and enjoy it. Usually for sexual pleasure.

The epitome of cringe

When the clock strikes around 2:00am and your eyes suddenly start to feel like they are two bottlecaps stuck to your face.
