brain mint 

A term used when someone does not remember a particular event or person and you must refresh their memory on the subject, just like a mint freshens your breath.

"Dude you remember that chick from last night?"
"No man give me a brain mint"

Brain Mint 

The need to refresh one's mind from a bad or uncomfortable thought or visual.

I saw my grandfather naked in the shower, and now I need a brain mint.
