Brain Freeze

Characters eating cold food or drinks too fast will get a "Brain Freeze". Almost universally a Comedy Trope. Brain Freeze will be treated as the most searing pain imaginable. Expect to see rivers of tears, screams of anguish, and the victim frantically clutching his head in agony.

Truth in Television; you most definitely can give yourself a headache by eating cold food too quickly. This is due to the blood capillaries in your sinuses; cold food causes them to constrict, and then experience extreme rebound dilation as they warm up again. This rebound triggers nearby pain receptors, which the brain interprets as coming from the forehead. You can recreate this effect when you put an ice cube on your forehead (and you don't have a headache, that is).

Now, if you want to prevent it, just lick your soft palate before diving into that milkshake and you should be fine. Eating warm or hot food can also help.

Advertising

 * A McDonald's commercial from two decades ago has a boy telling the audience that one of his lifelong ambitions is to become a scientific genius so that he could cure "that thing that happens to your head when you eat ice cream too fast." (Exactly what this had to do with McDonald's, I can't remember.)
 * A 1990s 7-Eleven TV spot was perhaps the Trope Namer. It featured a young man ingesting a Slurpee, letting loose a bloodcurdling scream, and then explaining: "Ugh. Brain freeze."

Anime and Manga

 * In the Cowboy Bebop episode "Mushroom Samba", a one-shot character is eating ice cream when a Chase Scene in progress passes him. He decides to join in, but rather than abandoning his ice cream, he attempts to gobble it up all at once. He does not enjoy the resulting Brain Freeze.
 * Used by Team Rocket in the Pokémon anime, giving the characters loads of ice cream and then stealing their Pokemon while they were disabled by the freeze.

 * In one chapter of Kochikame, Ryotsu bought a shaved ice maker and a big block of ice to make shaved ice bowls to eat which he got addicted and goes far as making sushi with ice rather than rice. His addiction got him severe brain freeze ends the chapter with him laying down with bags of ice over his forehead.
 * Ururu in Okusama wa Mahou Shoujo gets one from sweeping an iced drink. She does it again once she gets a refill.
