Sloppy Biffle 

The act of repeatedly striking a sexual partner with a sock full of semen, urine, and feces; similar to the beating of Gomer Pile in "Full Metal Jacket."
My girlfriend refused anal, so I gave her a well deserved Sloppy Biffle.

Skew-biff 

Dishevelled, rakish, disorderly, or unkempt. Used of hair, neck ware, or one's general disposition. Opposite of "rectilinear-biff." Origin unknown, but possibly derived from a misunderstanding of "skew-wiff." Usage peculiar to Brasenose College, Oxford.
"My word, Terence, with your tie at that angle, and your obvious bed-head, you're looking unusually skew-biff!"

"Don't worry: I get myself rectilinear in no time."

Stiff Biffy

Having a fully erect penis while wearing sweat pants.
"Dude, I got early the other morn'n and went to hardee's for a biscuit only to look down and see that I was totally sport'n a stiff biffy. The cashier called the cops when she saw the head peak'n out."

The Sisyphus of Biff 

From "Back to the Future" to describe the fate of Biff Tannen, marked by his repeated, failed attempts and subsequent punishment for his evil transgressions, muchly similar to Donald Trump.
We watched "Back to the Future" so many times, only to mock The Sisyphus of Biff.
