Man Brain

The most supperior of all brains. Compared to a "woman brain", the man brain has the ability to find directions, solve math problems, use common sense and logic as well as not being affected by drama/bitchery/feminism. Those with a man brain find life much easier and more complete than those with other forms of brains.

"Damn, his man brain is so big."

brain stew

i do beleive all the other definitions of the word, but i have to argue with the one about it not doing crystal meth, it clearly says "spun out in my room," which means that you are high on crystal meth, so maybe the song is a mixture of beth definitions, and if not, why did billie joe use the term, spun?

wow, i was listening to green day, and i was all spun our in my room and shit. green day kicks ass!

Brain Shovel

The theoretical sexual maneuver of sticking one's penis up another person's nasal cavity, as if attempting to shovel out their brain.

Look at the size of that chick's nose, she's a prime candidate for the brain shovel.
