As seen in the popular HBO television drama, True Blood, bouncy sex occurs when two people (preferably male and female)scissor and instead of an in and out motion, they bounce up and down repeatedly.

when in missionary position, the individual on top bounces up and down in a fashion in which insertion and withdrawal occur in midair as the individual on the bottom bounces up from the force of the bounce by his/her partner
