When an article of clothing or other item (toilet paper, food from the couch, etc.) is caught up in one's butt crack through suction alone, without the aid of a pants, underwear or pantyhose waistband. Not be confused with a wedgie, which is the seat or crotch of one's garments being caught up, no pun.
He stood up from the couch and had a potato chip crack butt.
