A motorcycle helmet. Specifically the kind that just covers the top of your head. They are mostly sported by riders on top of a American brand motorcycle, chiefly, Harley Davidson.
Hey Pete, good thing you were wearing your brain pan when that car slammed you. Your face is a mess but at least you can think straight!

Get the brain panmug. by Roger Bernardo July 9, 2009
Get the giving brainesmug. 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.

Get the Baby's Brainsmug. 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.

Get the hungry brainmug. 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.

Get the lamb brainsmug. 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.

Get the Lamb's Brainmug. When you pull your balls up above your member and let them hang out and over the top of your pants, giving the appearance of a brain.
