SIBFO

Pseudo-scientific acronym for Spinal Indentation Belly Fat Overflow. Sometimes referred to as "Crack", "Ass Crack", "Ass Cleavage", "Butt Cleavage", or "Butt Crack." This malady was first diagnosed on Puff.com.

John Goodman had some serious SIBFO goin' on when he was on Roseanne.

Dude, pull up your pants, too much SIBFO.

That chick's spinal indentation belly fat overflow was huge!
