look up any word, like donkey punch:
 
1.
The particular view of a woman's cooch when she is in the f.d.a.u. (clothes off, face down, ass up, c'mon) position.

Fur buns are also visible if your girl friend likes to impress you by standing with her legs spread and her hands flat on the floor

Seeing that little fur bun nestled in there makes you want to do AT LEAST one of three things: enjoy some bearded clam, get busy with the bun or tap that ass.
him: while I'm here, can I do all three?
her: sure you can!
him: I better get busy.
her: I am so happy that I have a fur bun!
