sidebowl 

To urinate while standing at the side of the toilet bowl, rather than at the front.

I had laundry on the drying rack in my tiny bathroom, so I had to pee sidebowl. S'all good though.

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!”
