Magillacutty

A word for either the greatest, dumbest, funniest, or most random thing someone in Lingo's apartment has done. At least it's better than "son".

(Hey dog that was magillacutty......), (For real you did that she was Magillacutty), (Pass me the drink I'm getting Magillacutty)

McGillicutty

This is a good filler word when you can't think of the name of a particular object or person you want to reference.

Go into my office and grab the McGillicutty off of my desk.

Hercules MaGuillicutty 

A sexual act including leg throwing, flexing of arms, and moonshine. The "Hercules" is performed with a woman while she is laying on her back. The man, while thrusting, takes a shot of moonshine without swallowing, then lifts the womans legs up with his arms as he flexes them. Directly after this movement the man pulls out and cums on her twat. He then spits the moonshine on her twat, causing an intense burning sensation. This is followed by a feeling of complete euphoria.

I heard Chris gave her the "Hercules MaGuillicutty" last night. Their relationship is over.

McGillicutty

Used with the individuals first name. Any guy who's completely clueless and irrelevant at work. Named McGillicutty because this name was used often to describe an off camera ding-dong coworker on mid 20th century television. Not to be confused with a Boomer who actually comes from the mid 20th century.

"What the fuck is (First Name) McGillicutty doing? Stupid mothafucka over there in the corner just staring at the wall and I told him to move those boxes an hour ago!"
