A tiny vagina on a woman that has no visible lips. It appears to be a just a small slit and is often difficult to see. Hence the term "peek a boo where are you?"
Mary had the smallest peek a boo I've ever seen. It was so small I had to feel for it because it was difficult to see with the naked eye.

Peek-a-Boo
While having doggy-style sex in a dark room, you switch with a friend without her knowing and then exit room and wave to her from her window
When just the tip of your man's petite junk happens to make a brief appearance out of the bottom of his inappropriately short shorts. See the pinky. Antonym: the brain.
