This is the act of throwing up warm chunky vomit onto a partners genitals during oral sex. As disgusting as it sounds, surely there are people out there (like those into shit porn) who enjoy this. It is generally an accidental act triggered by a gag reflex or perhaps a very yeasty vag, but may be used purposely as an act of revenge or spite.
