Side Bowl

To urinate on the side of the toilet bowl, avoid the water in order to reduce the sound of the liquid release.

Dude #1- I drank so much last night, I was pissing all
night.
Dude #2- Really?!? I didn't hear you
Dude #1- That's cause I side bowl'd it

Side Bowl Sit

When someone poops (usually a child) and sits there for a while until the poop becomes stuck to the sides of the toilet bowl. (Usually discovers by a parent or older sibling later)

“Dang it Billy! You left another Side Bowl Sit! I’m gonna kick you out the next time you do it!”
