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.

Anthony hadn't gotten laid in 5 weeks, and couldn't take it anymore, so he gave in to temptation and went dumpster diving

You are a jungle trudging dumpster diving piece of shit!!

Looking for hook-ups or relationships, particularly with women, who use online dating sites or personals ads. (The logic being that almost any girl can get laid without having to advertise for it... and the ads are society's dumpster for those who can't.)
You can tell he met that skeezy chick on an online hook-up site. Yikes! But, hey, you can't expect to find quality when you go dumpster diving.
