bat brain

a move personally made up from the batwing, a cruel joke, mostly done by other teenagers, where you take your scrotum, spread half of your sac out with your hand, and cup the other nut in your hand like a brain. takes a while to get right, but when accomplished, is better than the batwing

I flashed robert with the bat brain, and he threw up!

Big Brain Moment

If you're a (big brainer) then you've most likely experienced a so-called "Big Brain Moment". But to all you low-class MacDonnals workers, a big brain moment is when you get such a good idea, that you just have to yell it, so everyone can hear how clever you are.

Me a highly intellectual: Hey (Brad)
Brad: Ya bra
Me: You know what I just got?
Brad: Nah brah
Me: I just had this really good idea, but I ain't gonna tell you it, because, you're not clever enough to understand my superior brain (Laughs in a high IQ voice), boy oh boy I do like when I get these Big Brain Moments.
