"Dumpster" is tacked on to the word "diver." A "diver" is short for "muff diver." When one adds "dumpster" to it, then the conotation is obvious: someone is diving into a cavernous, dirty, nasty ... cavity. But take the origin of "Dumpster!" Usually it has "cum" in front of it (as in "cum dumpster"). So now we can think of an alternate definition as having to do with sloppy seconds, or thirds ... or more. When "diving" in this manner, there is usually an echo and vile residue involved.
My face was all sticky and covered in pecker snot at that party last night when I decided to be a dumpster diver with that nasty skank.

When ones ass crack sticks out of the back of ones loose-fitting pants and under britches in the same manner as a plumbers crack. The reference comes from the thrilling temptation of dropping a couple of pennies down there.
I could see every hair and dingle berry in his plump piggy bank when he squatted with his back to me to pick up the quarters I threw on the floor.

Residual grease found in ones butt crack. It may stem simply from sweat or sex liquid having oozed back there (or maybe sex actually having taken place there with the aid of KY warming liquid or baby oil). The person with the malady may feel an odd slippery sensation when they walk, shift in their set, or sit down.
I felt my butt cheeks slide in opposition to one another after having an explosion of butt grease caused by my queef barfing out lots of spunk and splattering my back door.

Dry Dock: v. To emulate sex with an engorged fuck stick but fully or partially clothed. Usually done by teenagers who aren't ready to do the real thing (maybe she's a cherry). It comes from the term for a ship out of water, as this teenaged boy's "vessel" is not going to contact any liquid!
