Slippery Steve 

When, while taking a dump, one allows a turd to partially leave the ass, and then pulls it back into and out of their asshole repeatedly. Also called "shit fucking".

Rob: "What took you so long in the bathroom?"

Steve: "I was giving myself a Slippery Steve."

Rob: "That's.... terrible."

slippery slut 

A female (human or otherwise) who is shady and not to be trusted. A woman who improves her situation through questionable means.

Ron: "I met this girl the other night. I took her home. When I woke up in the morning she was gone and so was all my money and my trees"
Markus: "Damn! what a slippery slut! If you every see her again you should take her home and donkey punch her"

slippery scotsman 

The act of blending watery diarrhea with a shot of Scotch whiskey and serving it to an unsuspecting victim.

I served Jim a Slippery Scotsman at Evan's party last night after finding he fucked my girlfriend. After he felt the warmth of the glass and the smell of the drink, he proceeded to vomit everywhere!
