As opposed to what dumbass "beezy" is saying, it does not refer to the lights of a car!
Brains can either be "head" ie oral sex or when used in reference to a car it referes to the top (convertible) or lack there of. For example, when someone "buys an old school and blows off the brains", they are simply buying an old classic car and then getting it custominzed to have no roof or to be convertible ! The other variant of this is when you say your car has the titties out = topless
I am so sick and tired to these little white kids listening to hiphop and them having no idea of the slang, but they think they do ! that shit is so fuckin funny and pathetic !
A one-hand grip maneuver performed on a scrotum; either your own (usually during the penis showing game), or someone else's (during oral sex, foreplay or cbt). The scrotum is grabbed near the base, squeezing until the skin is tight and the testicles beneath bulge out to form the appearance of left and right "lobes" of a brain.
