good idea fairy 

Military term; An evil mythical creature that whispers advice and ideas into the ears of military leadership, causing hundreds unnecessary changes and countless wasted man-hours every year. The Good Idea Fairy should be shot on sight if she is seen in your area.

Great! The CO has says that we need to provide a 24 hour guard over the weekend for the empty tents out on training area 17. He must've been visited by the good idea fairy.

You have no idea 

A response that emphasizes the irony of the preceding statement.

Woman A: Your husband is unfaithful?
Woman B: You have no idea. (Husband has a gay lover)

Man A: Heard you a crazy weekend!
Man B: You have no idea. (Man B is a secret agent who used a party as a cover for a mission)

Mario, the Idea vs Mario, the Man 

The best work of literature ever. The author chose his words carefully to create such a masterpiece. Words like "Turts" "Turty" and, of course, "Perchance" only help the writer prove his point.

Person 1: "Have you read 'Mario, the Idea vs Mario, the Man' yet?"
Person 2: "What is that"

Bad Idea Jeans

Metaphorical article of clothing, the invocation of which indicates the "wearer" is exhibiting spectacularly bad judgement. Inspired by the 1990 "Saturday Night Live" sketch of the same name.

"You left your bike outside last night without locking it up? Those Bad Idea Jeans look great on you."

"I can't believe I went home with Butch last night. That's what I get for wearing Bad Idea Jeans."
