Italian guillotine

A sex act where one party holds their penis on a coffee table while the other covers their bare foot in marinara sauce and olive oil before stomping on it. A variant of "dick flattening."

"My girlfriend has gotten bored with our sex life, she wants to work food into it."
"Like she wants to pour chocolate sauce on each other?"
"No, like she wants to give me the ol' Italian Guillotine."
"That's a-spicy dick flattening!"

The Slimy Guillotine

When a girl with her 4 front teeth are chipped diagonally, resembling the angle of a guillotine, is giving you head with ounces of lube being used and slices down cutting the tip of your penis.

"Bro, some cracked bitch gave me The Slimy Guillotine. Shit hurt."
