A scientific law formulated by Sir Isaac Newton telling the likelyhood of a female having sexual relations with a male, as expressed in the equation:
M= Muscle definition
v= Moral Values
S= slut value
Jon: Do you think Ashley will fuck Michael tonight?
Matt: No, he's not enough of a douchebag, so it does not satisfy Newton's 69th Law.
When you procreate in the bed or cab of a Silverado, Colorado, Canyon, Escalade EXT, in the back of a Tahoe, Yukon, SRX, Trailblazer, Escalade, Suburban, Equinox, Traverse, Canyon, or Acadia, Enclave, or in the seats of Lacrosse, Camaro, CTS, DTS, STS, Corvette, Impala, or XLR Roadster; But not Aveo, or HHR. Those are for pussies.
Jon: "Dude, Does Mike have Ashley in his Tahoe?"
Matt: "Hell yeah, He's getting Chevrolayed in the Wallgreens parking lot".
Simply, when one's face breaks out with such ferocity and cunning overnight that it flummoxes all those who knew him/her.
Jon: "Dude, Mike's face is Dufresning badly today."
Matt: "I know dude; who would've thought. He used to be such a good guy"
