Wal-mart (v): To stop at a Wal mart to use the restroom facilities only, in a conscious commentary on their business practice. Derived from the ubiquity of Walmarts in small town America and coined in College Place, WA, where Walmart single-handedly destroyed the economy of the town, now home to their very own strip mall.
Usage: Can we stop soon? I need to Walmart.
Okay, it's a road trip thang.
