Brainfood 

Information that feeds intellectual craving.

Did you know that the average lightning bolt is hotter than the surface of the sun? How's that for some brainfood?

"Holy cow man, my chemistry final is huge! I've had so much brainfood today that I'm shitting out of my ears."

brainworm 

An image, sound, or other thought (usually one that you don't want to think about) that gets stuck in your mind. The best way to get rid of a brainworm is to replace it with something else (just don't think about your current stuck thought, though).

A brainworm is different from an earworm in that an earworm is a song that gets stuck in your head, while a brainworm is anything that gets stuck in your head.

I have a brainworm. I can't stop thinking about the disturbing meme I saw last night.

Braintree 

A large suburb of Boston, MA that is most certainly better than its neighboring rival-town, Weymouth. Also, until it was divided and re-named, Braintree contained all of Quincy, now the largest and most notorious satellite city of Boston. AKA: B-Tree, The Tree, Bra-In-Tree

Weymouth wiggers came to Braintree looking for a fight, but got their asses kicked and subsequentially realized that they were neither black nor Eminem.

Schiff for brains 

When someone lost access to their bitcoin due to technical illiteracy.

Peter never learned how to backup his bitcoin seed phrase and lost his private key. What a Schiff for brains!
