A contagious disease that affects young men (mostly) whos buttcracks are to high to fit in their pants. Most commonly found in groups of swagfags, ghetto wannabes, as well as "gangstas" as they put it. Can be cured with a belt or pulling up your pants. Also known as sagging.

The horizontal crack formed between a womans butt and her upper leg. Usually, this crack is found in latino, or african women. A pseudo crack can be created when a woman is wearing pants that create the allusion of a HBC.
