swag-muncher

One who (particularly of younger age) takes the leftover bits of another person's (particularly older) swag in an ongoing game of Pacman-esque swag stealing. If you've ever seen a fish consume algae and other fishtank residue, you've seen the act of swagmunching far before it evolved into the common practice that it is today.
