Greasy Slinky
After you, and your buddy are finished double teaming a female from both ends (and thus have "greased her up" from both said ends), you throw her down the stairs. If done right she will look like a slinky going down the stairs.
Dude, that chic from last night really wanted to have breakfast together. I told her I got a better idea: I called Aaron over and we did a greasy slinky on her, then closed the door behind us big bro high five.
