The Hamburger
A penis trick in which you fold your dingy between and under your beanbag. Proceed to hold it there and twist the entire unit as a whole. Now your dingy should be between your balls in the horizontal position. If done right the outcome will strikingly resemble a hamburger. Comes with a sesame seed bun.
