bird brain

Somebody who doesn't understand math and will never understand. He will utter stuff like: The proof is brilliant. It uses mainstream mythmatics to demonstrate the bullshit being taught by the BIG STUPID. It accepts infinity as being valid.

John Gabriel, you wont get it with your bird brain.

Brain Boog

A booger that feels like a hard boog when being picked, but is attached to soft gooey boogs which when pulled out, seems like it is attached to the brain.

Oops, I thought that was a hard boog that I could quickly pick, roll, and flick. I had no idea it was attached part of my frontal lobe. That was one hell of a brain boog.

Danny: Sorry man I think I have cloud brain, I can't focus on anything.
