Brain burn 

When a person sees an event or an image that is so horrible they will never be able to forget it.

I walked in on my parents having sex and got instant brain burn!

Brain Burn 

The opposite of brain freeze, for when you eat something spicy.

That bowl of spicy ramen gave me brain burn.

Burnett's Brain 

When you drink copious amounts of cheap liquor (traditionally Burnett's Vodka) one night and the next day your brain is essentially useless.

Dude I got so drunk on shitty liquor last night I can't even talk today - I've got total Burnett's Brain.

Burning Brain 

When all you can think about is about Burning Man even though you have a job, deadlines, a wife, a mortgage, pets, etc. The condition of not being able to focus on anything else but Burning Man.

"Baby , I'm so sorry I forgot to mail in the mortgage check this month, I've got Burning Brain."
