Someone who volunteers for research studies that mess with their brains (usually via psychoactive drugs) for some cash.

Brain Burglar 

one who in a conversation, discussion or argument deliberately or inadvertently makes ridiculous statements or repeats already invalidated points causing the other party lose their goddamn mind.

trevor: man, Charles is fucking retarded! i was trying to explain to him why the Shamwow is just a piece of corporate slag used to channel the masses into following a consumer driven conglomerate and all he kept saying was "get over yourself, Olympic divers use it"...

steve: i know man, dont worry about it, he's a goddamn Brain burglar.

brainema 

What is required after a long session on some the Internet's stranger zones, such as 4Chan. Voluntary amnesia.

I wish I could have a brainema right now. I've just seen 2 chicks, one cup.

brain-dead gawker 

someone who gawks in your face--inappropriately, of course.

You are on a bus and someone wearing headphones or who looks like they think they're watching a TV program gawks in your face. You don't bother to say "Hello!" (or "WTF?!") because you already know they won't answer nor even blink, but instead you heartily remind yourself under your breathe, "(It's just) a brain-dead gawker (oh yeah!)"
