What is Brainfire?
1.
The opposite of brainfreeze, this happens when you eat something very spicy (it works mostly with that hot Chinese mustard in restaurants) and it sends a burning sensation up your nose and into your skull. This happens even more frequently when you eat more of it while the feeling is in your nose...
Usually dissipates in a few seconds
I just dipped that fried noodle in too much hot mustard, now I have brainfire!
