The nectar of the gods. The greatest drink ever to exist; in fact, the greatest ANYTHING ever to exist.

Some people drink multiple gallons of chocolate milk per day. These people have been known to hurl buildings into other buildings, have sex for literally days nonstop without getting tired, throw punches at the speed of light, and travel through time.

Someone invented Powerthirst in an attempt to replicate the effects of chocolate milk. They failed miserably.
