Similar to a mall rat
. WaRats are socially rejected kids (and sometimes adults) who loiter around Wawa's aisles, parking area, and do no good to anyone. They almost never buy anything, and when they do, it's from money they bummed or yoink
ed from fellow WaRats or actual consumers.
Dude, let's go around the other entrance, those WaRats are crowding around the front entrance. They look like Girl Scouts, only they aren't there for a good cause... or any cause for that matter.
