beercussion 

The condition experienced the day following extreme over-consumption of beer, when symptoms of a concussion are exhibited; e.g., head pain, dizziness, loss of coordination, double vision, vomiting, nausea, memory loss.

Akin to a normal hangover, but specifically due to beer consumption.
