brain milk 

A humorous animated cartoon shown after an extremely scary horror movie which has a calming mental effect similar to the physical effect of drinking a glass of milk right after eating extremely hot/spicy Mexican cuisine.

Gee, that Woody Woodpecker cartoon the theater ran right after that scary movie was real brain milk and made me feel better, less likely to have nightmares tonight.
