A very old French invention, typically with a large wooden frame, and a very sharp slate of metal attached to a rope. The person being executed is then laid down in position, the rope is pulled and they are decapitated.
"Today, at the hanging, we have two contraptions instead. An old-fashioned rope, and our new invention, the guillotine. It is swifter, and cleaner and has no chances of survival."

Aug 11 Word of the Day
A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
"My boyfriend has a total case of brain worms. He told me the cat was bugged so the Feds could listen in on us having sex..."

or

"You totally stumbled over that entire sentence. Can't speak English all of a sudden? What, do you have brain worms?"

Extreme woman muffin top that you need to lift up when you wanna engage in sexual intercourse with a ginormous rhino of a chick. When that muffin top flops back down after insertion, it basically does to your dick what a guillotine used to do to people's heads.

A sexual position involving two females and one male participant. The two females spread legs and meet vagina-to-vagina (also known as scissoring) and the male inserts his penis into the center; so named the guillotine because his 'head' gets cutoff by the scissors.
I lost my crucial head to a guillotine with two skeezers I took home from the bar last night.

v. to hide a boner putting your penis in the natural/straight-up position. The penis log is well hidden and unnoticed, but the head exceeds the part where your belt fits...if someone lifts your shirt, they'll see your head saying hi
