Word used by fat, stupid, lazy males to refer to oral sex. Since these men are not accustomed to using their brains and are entirely unfamiliar with this organ, they move this function to other parts of their body. This not only kills the reliance on the brain, but allows the man to continue killing this organ with beer, fatty foods and a lazy attitude.
"Good thing all this beer, burgers and sitting around all day watching football isn't harming my brain, since brain means blowjob!"
"She's a very freaky girl,
She get it from her momma.
First you get her name,
Then you get her number.
Then you get some brain in the front seat of the hummer."
