buttbate

The act of violently shoving your thumb into your asshole and shitting as you do it, this is usually done for sexual pleasure. (Male or female)

Me: Dude, I just buttbated, it was amazing.
Billy: Does your thumb stink?
Me: (Sniffs thumb) FUCK YES! There's fucking shit all over my hand! I forgot to clean up I guess...
