LOOK OUT! It's coming to a brain near you..... I don't have it (yet), but I wish I did (sorta). Yeah, I'm a big "word nerd" and I love the word "sphenopalatine gangleoneuralgia" it's the scientific term for "brain freeze" or "ice cream headache". Pretty cool, eh?
If you read further on the link, you'll see that pressing your tongue up to the roof of your mouth can help get rid of brain freeze. I've tried it before and it helps a bit. It's better not to let the ice cream touch the roof of your mouth in the first place!
