One who is overweight and out of shape from spending too much time playing video games, watching tv, sitting in front of a computer and/or basically rotting away on a couch. One who gets up just long enough to grab a bite to eat.
Inspired by the lazy, fat technogeek humans in the Pixar animation Wall-E.
Look at that Wall-E over there at the snack bar. I'm surprised she even had the energy to get her fat ass off the living room couch.
