bitch fog

The stanky smell that emits from an unclean female's crotch. Similar to nutsack musk on a male - both can be smelled from a distance on a hot summer day, or while either is doing the walk of shame the next morning.

Friend 1: What IS that rank stench!?

Friend 2: (points at a hooker) Eww, it's gotta be her bitch fog!
