volcano

an act in which, when a fart is coming on, the asshole is elevated into the air either by situating one's self on all fours with shoulders to the floor or by lying on one's shoulders with knees to the ears, causing the asshole to open and remain so. once this state has been achieved, air can be repeatedly sucked in and blasted out, causing a signature sound that is difficult to replicate by other means.

I felt a massive fart coming on and was able to volcano for five minutes straight.

shadow turtle

A turd that slides down into the toilet in such a way that you can just see its 'head' poking out.

I was trying to see the corn I ate last night, but it was a shadow turtle.
