Stopping at the store or usually a quickie mart to grab and throw down some snacks while on your way to eat at someone's house. Usually because you know there's going to be little or no good food there.

(on the way to a party at some chick's house)
Jim: Isn't she a vegetarian? We'd better stop and get some store d'oeuvres. I can't eat that shit all night.
