Obutt
Obutt is when your butt looks like a squishy oval and stuff slides in and out of your ass like it's on a greasy slide.
My Obutt is so good I can eat a whole pizza and still fit in my pants.
I told my friend he had an Obutt and he laughed so hard he peed his pants.
My Obutt is so strong it can hold a full can of soda and not leak.
