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!

buttstonked 

Being so twistedly fucked up (extremely inebriated in some form) that you literally can not and do not want to do anything.

X: Dude, that party was intensity in ten cities!

Y: Totally so dude, let's roast these righteous herbs and get thoroughly buttstonked to celebrate!

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."
