Flapped Ass 

Similar to cleft lip, flapped ass is a chronic condition in which either of the two glutei maximi (buttcheeks) recedes to form a significant gap, aside from the gluteal cleft (buttcrack).

1. "1 in 3 children have been diagnosed with flapped ass. For 15 cents you can save a child's ability to sit in a non-tilted position."
-"ROFL"

2. "Yo why is my right butt cheek so much bigger than the other?"

- "HA YOU HAVE FLAPPED ASS"
