Sinister Stanley

When a man marries a woman, and proceeds to perform bedroom antics with his wife's sisters, because this guy is void of any kind of moral compass, and/or is just a complete douchebag.

Girl - "I can't date that dude, he's such a Sinister Stanley!"

Girl - "Did you hear about Dave? He totally did a Sinister Stanley on his wife".

Man - "I have so much respect for Brian. He Sinister Stanley'd the shit out of his wife!".

sinister slipper

Waking up 20 minutes before your roommate and nutting in their slippers so that the slippers are damp and sticky when they put them on.

My jackass roommate screamed when he put his nasty ogre feet into his sinister slippers this morning and it was hilarious.
