lamb brains

The act of taking only your ball sack out of your pants, choking the balls tightly to the bottom of the sack tightly with your fist, and then standing nonchalantly next to a friend in an attempt to get him or her to look them unknowingly. When and if they do look, you must bleat loudly, mocking a sheep.

When a man flashes his testicles (and only his testicles), pulled up and taught to simulate a lamb's brain. Usually used for offensive humor after the question "want to see a lamb's brain?" or "have you ever seen a lamb's brain?" The person questioned is usually not given time to respond properly before being flashed.
