Pinky and the Brain It

The act of getting so sun burnt that your skin peels and you become all pink. Then you throw on a speedo and let your balls hang out the side.

Bro, I got so sun burnt on vacation I'll have to pinky and the brain it all week in the name of comedy.

baby's brains

When a man grabs his nut-sack, squeezes it from the base of his body, seperating the scrotum with a fist. The balls are in a "streched sack" state, which looks like the brains of a baby. Ball-hair accentuates this optical illution.

Hey look eveyone, baby's brains!!

Cum brain

When you’re in a mental state of horniness and you can’t think straight. Usually the stage before post nut clarity.

Sarah: *out of breath* Did you say you loved me?!?
Bobby: *also out of breath* Oh shit my bad I had cum brain. Sorry I wasn’t thinking straight.
