Wal-Skank
Derogatory term for a (usually younger) female walmart shopper, implying trashiness or tackiness, lower-class status, poor hygiene, flakiness, and a scrawny, pockmarked sort of ugliness. May also imply prom...iscuity, but not necessarily. Can apply to any race, but most commonly used to describe white trash.
Did you see that Wal-Skank over by the beauty products? I could see her everything hanging out of that mini skirt.
