The Ruda Tuba - (rooda toobe a)
After fucking a chicks yatch
hard (preferrably in the doggy position), you proceed to flip her on her back, grab her by the ankles, bend her knees to her chest, and make her
queef. Repeat this maneuver by pumping her legs as if you were playing a tuba. "Ruda" is
short for Rudimentary.
