Motorboating

The placement of one's face, specifically the mouth, into the area between a well-endowed woman's breasts, followed by a rapid shaking of the face in a side-to-side motion accompanied by yelling. The resulting sound that is created sounds similar to an outboard boat motor.

Sherry was wearing a low-cut top and Mike approached her and started motorboating in her cleavage.

Dirty Bayou Motorboat

The act of motorboat-ing an attractive woman's ass instead of her breasts.

"Man she's got a great ass. I'd love give her the Dirty Bayou Motorboat"

"This guy motorboated my ass last night like it was my tits and then he said something about a bayou..."
