The Catavalanche 

The act of a man lifting up his large, floppy abdominal pannus before receiving fellatio. Immediately after coitus he releases the sweaty mound and it collapses onto the face of the unsuspecting female while she is still attached to his flaccid member.

Jackie was always a fan of hookin up with the big fellas... until Ron decided to crush her face with the catavalanche.
