Wal-farter
A nasty, fat, greasy-haired piece of white trash who shops only at Wal-Mart, and thinks Kathy Lee Gifford Clothes are Haute Couture, and buys everything in jumbo economy sizes. Wal-Farters are most common in Southern US States.
"Did you see that ugly, fat, Wal-Farter heading this way carrying the 100 roll toilet paper economy pack on her head?"
