Jerk waddle

The act of walking after being interrupted masturbating where the erect penis makes pulling the pants up difficult or hard so the pants stay half mast causing the subject to waddle.

I was so high I forgot I ordered the pizza and cinnasticks and decided to rub one out to a midget menos a trois when the doorbell rang... I had to jerk waddle up a flight stairs and past my sleeping mother. Then I realized I didn't have a pen.
