motorboatable

Refers to a lady with ample breasts, or ample everything, whose physique built to perform a motorboat would be an easy task. The motorboating may be done anywhere on the corpus where one can press the face in between any skinfolds, 'as long as the cheeks are warmed'.

Before Oprah Winfrey lost all that weight she was extremely motorboatable. Now she still retains some motorboatability, but only of the more conventional variety.

motorboating

A great way to end an awkward conversation with a girl you don't want to talk to.

"This girl was in my room and I couldn't take it anymore so I motorboated her. After the motorboating she left."
