This usually occurs when a man hasn't been layed in ages, and is incredibly desperate. He will go to a bar, get really trashed, and leave with the nastiest chick there, a total scrump, just because he knows he's gonna get some. This is also a great insult.

Dumpster Diving is the term given to 'going down on' a really really ugly, skanky female. Generally her loose-as-a-goose, diseased pussy is considered as the 'dumpster'.
I walked in and caught you dumpster diving your fat ugly sister. Whats up with that dude? This definition was made up on the spot.
