The raw tender period that your
anus goes through after you have a violent bowel movement, resulting in tenderness of the
anus where you cannot sit down for a few minutes following. You must
stand still and wait for the feeling to go away.
"
Guys, I can't sit down yet, I have Supplebutt"
"I
will have a seat once my Supplebutt goes away"
"Oh man, I've got serious Supplebutt, give me a few minutes to recover before we
go anywhere"
