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

TruthInTelevision; 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.

* 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 [[BuffySpeak "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 TropeNamer. It featured a young man ingesting a Slurpee, letting loose a bloodcurdling scream, and then explaining: "Ugh. Brain freeze."

* In the ''Anime/CowboyBebop'' episode "Mushroom Samba", a one-shot character is eating ice cream when a ChaseScene 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.

Thomas manages to win, bypassing his immunity to normal cold foods using a GiganticGulp slushee called the [[TurnedUpToEleven Cold Cubed]], but he goes catatonic because of the freeze literally spreading through his brain. This leads to a FantasticVoyagePlot where Mordecai and Rigby have to shrink down and deliver a payload of dynamite to the core of his brain to thaw it out. They meet a slightly less anthropomorphic goat in there, [[GhostInTheMachine representing his brain]] and the freeze is spread by an anthropomorphic slushee cup [[PokemonSpeak only capable of saying "freeze"]] with an Inuit dogsledder as a translator. It's that kind of show.
