Superchilling is the art of putting a beverage inside the freezer compartment of a refrigerator for roughly 30 minutes, a good practice if you're needing cold drinks in a hurry.
The reason for the word "super" is because chilling a drink only involves a fridge and takes about 5 hours or so.

> I can't drink water in a warm state, I always have to superchill it beforehand.
