Noun - The clear, slimy, snot-like substance produced by the ass when a fart is miscalculated, or when one sits on the toilet in anticipation of diarrhea, but naught but an airy, wet fart with BOOTY GOO is produced.

Booty Goo is so slimy, that it's difficult to get traction with the toilet paper when wiping your ass. It is also characteristically free of actual fecal material.
