Flap Slapper

A female who in an effort to encourage further vigorous copulation slaps her own genitals as if beating a war drum. Rhythm is usually comparable to the Christmas Carol “ The Little Drummer Boy” with encouraging words in place of the lyrics and vigourous slapping of the hand on the genitals in place of the “Parumpa pum pum” sections.

Dude, Maria is such a Flap Slapper. I can't get enough of her.
