Similar to the mallrat, the rural Wal-rat hangs out at the local Wal-mart because his or her town is too small to support an actual mall.
Philip: So... Earl, what is there to do for fun around here in Whiteland, IN (real place, look it up.)
Earl: Welp, you can come wid us down to Franklin to the Wal-mart so we can play some video games while Jeff flirts with the chick from the gun and tackle section. I also heard that the Mickey D's there brought back the super size, we can hit that up after we pick up the new Nickelback cd.
Philip: Nah, that's cool. I'll just stick with this porn. I'm not really down with the Wal-rat scene anyways.
