When one sends a fat shit and has a hairy butt, causing the excrement particles to become stuck in the hair. If not throughly wiped, in can cause the butt flaps to become stuck together. Can be a somewhat painful ordeal.
Damn bro my butt hurts...
Why what happened?
I got shit tasseled...
Wow bro you've got to wipe better!
