Buoyant 

Something that’s like really unexpectedly cool. (The opposite would be if something were to “sink”)

Wow Amy, that party was buoyant. I can’t believe we almost didn’t go.

Opposite:
Omg Amy, that party sank. Can’t believe we thought it would be fun.

buoyant poop

The type of poop that doesn't flush down the toilet on the first try.

I don't understand how people don't watch to see if their poopies go down. Sometimes they are very buoyant poop.

buoyant bum

A bum to waste ratio and size that causes an individual to unintentionally float to the surface of the water when swimming; flotation typically occurs bum-first in extreme cases.

Dang dude, with a buoyant bum like that there is no way she can go snorkeling with us.

Buoyant Pendulum 

A sexual position where a man suspends a woman, who spreads her arms and legs straight out, by holding on to her arms and suspending her legs with his own. While suspended, the man then proceeds to perform anal sex on the woman by raising and lowering the woman with his arms and legs. This is one of the most tiresome and difficult sexual positions known to man. To perform, one must have a large muscle mass.

Bro, those months at the gym finally payed off. Me and my girlfriend tried out the Buoyant Pendulum last night and I kept it going for seven minutes!

buoyant terd 

Not quite the size of a turd, similar in size to a terd.... A bouyant terd is feces that floats to the top of the water, usually because of high amounts of meat a diet.

There was a buoyant terd in the toilet at school.
