A white trash/over-weight/red neck/gangster/wankster/greaser all around trashy person that lingers around walmart not really looking at anything but not really not shopping at the same time. A lazy browser. Looks as if they have the IQ of a farm horse. And probably smells like one too. Trotting around walmart simply being in the way. Hanging out at walmart is their favorite past time.
Wally-dirt.
That crazy neighbor you have or have seen in movies that collects things that look like they've been bought at goodwill and decorated their yard with it all.
