Wikipedia: Ice-cream headache
An ice-cream headache, also known as brain freeze, cold-stimulus headache, or its given scientific name sphenopalatine ganglioneuralgia (meaning “nerve pain of the sphenopalatine ganglion”-and is also considered a misnomer since the pain nerves have nothing to do with the sphenopalatine/pterygopalatine ganglion, but travel along the trigeminal nerves described below), is a form of brief cranial pain or headache commonly associated with consumption (particularly quick consumption) of cold beverages or foods such as ice cream and ice pops. It is caused by having something cold touch the roof of the mouth (palate), and is believed to result from a nerve response causing rapid constriction and swelling of blood vessels or a “referring” of pain from the roof of the mouth to the head. The rate of intake for cold foods has been studied as a contributing factor.
 
The term ice-cream headache has been in use since at least 31 January 1937, contained in a journal entry by Rebecca Timbres published in the 1939 book We didn’t ask Utopia: a Quaker family in Soviet Russia. The first published use of the term brain freeze, as it pertains to cold-induced headaches, was on 27 May 1991.

In 1994, 7-Eleven coined the term “brain freeze.” The word was developed to explain the feeling people get when drinking a Slurpee.
