The art of squeezing the scrotum tightly so that it looks like a cats brain. Typically hung outside of the pants in an attempt to get someone to look at it.
Have you ever seen a cats brain? Similar to asking if someone has something on their shirt.

When you squeeze your ballsack really tight and the balls are on the top it looks like a small brain.
