Buttster 

A fat lard that is mean to everyone and deserves to have their nipples chopped off and fed to a parrot.

International Buttstretcher Day 

A holiday celebrated every August 4, enacted by cs188 in 2016. Not much is known about it, but as the day's name suggests it likely involves stretching butts.

"WOO-HOO! It's International Buttstretcher Day, ha-ha-ha-ha! Awww yeah......awww yeah......"

doing the buttstroke 

Slang for when someone propels themselves through a still body of water, usually a swimming pool, entirely by passing gas.

This amazing and talented young woman apparently has the most powerful farts on the planet; I watched her doing the buttstroke the entire length of the high school gym pool!

buttstroke

the act of striking someone with the buttstock of a rifle, carbine, or shotgun. This is in contrast to "pistol-whip," which is the act of striking someone with a handgun, while gripping either the handgrip or the barrel/slide, but more commonly the latter.

"The brave Marine, having expended his last magazine, but lacking a bayonet, saw fit to buttstroke the charging enemy combatant."
