belly on back

A sexual position where you cuff your gut up, sit it on her stomach, press your weight against her stomach, cut off her circulation off and at the same time you hump the shit out of her.

blow back

(noun) In a convertible it's the (somewhat surprising) way the air blows from the back of the car toward the front. Many convertible drivers wear hats to reduce the effects of blow back. Fancy convertible makes such as Mercedes, BMW and Porsche often mount a screen behind the car's front seats to reduce blow back to those passengers.

Red thought he was all cool in his convertible until the blow back pushed his cap over his eyes and he ran down that mailbox.
