It makes a strong statement - “I’m a Moron”.
The TV show “The Wire” had a scene where a kid is walking by a police car with his baseball cap turned sideways. Two policemen in the car motion the kid over to them and ask him a question. “Where did you get that cap…I’ve been looking for one with the bill on the side for months.”
The kid never knows they’re playing with him and explains how it’s just a regular cap but turned sideways. I fell out of the chair laughing so hard.
