buttstank 

This word is used for fat people that smell horribly bad. It doesn't matter if their asses are clean, as long as they smell bad, its always considered to be buttstank.

That Charlie has mad buttstank, and I want to suck his weaner.

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!

vestigial buttsack 

When a person is born with the parts to form a butt (butt cheeks) but no flesh ever properly forms in it, so that the prson doesn't have the natural roundness of a butt and are therefore forced to sit on the extension of their thighs for lack of a natural butt. Or in simpler terms- lack of butt meat.

Hold on, is that Crystals's thighs or just her vestigial buttsack that's creeping from the top of her jeans when she bends over?

bullstankles 

The combination of the phrase "Bull shit" and "Stank". Typically bull shit is around the ankles so it gets put at the end of the word.

Jesse: WTF! what is that brown stuff around my shoes?
John Paul: THAT'S SOME BULLSTANKLES!

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!
