Mom Brain

Lack of normal brain function that the non mom does not possess. After birthing a child, you forget things frequently and don't remember what you did 5 minutes ago.

Oh geez Gina, looks like the mom Brain for you again!

Lamb's Brain

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.

Peter: "Want to see a lamb's brain?"

Brian: "Wha...?"

Peter: (shows)

Brian: "Ewwwww, nasty!"

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.

That lousy Ralphy got me to look at his lamb brains the other night… and it was while I was eating too.

Baby's Brains

A man's scrotum.

The balls, particularly when it's chilly and they're tucked up tight against the body. The foldy skin looks like the brains of a tiny baby.

"Ugh, I just caught a glimpse of your baby's brains...put those things away!"

hungry brain

An act, usually public, in which a man hangs his scrotum out of the fly of his pants, pulls the skin tight around one testicle with his hand, and squeezes rhythmically, resulting in a veiny, throbbing effect reminiscent of a 1950s science-fiction monster.

Usually considered vulgar.

They're still talking about the time he walked into Denny's and flashed the hungry brain.
