a 24 hour drinking game in which the participants have a block of 24 hours to drink as much Natty as possible. There are two divisions; the Light and the Natural. The mortality rate for Nattyholic is very high, and typically the winner is the one who does not die.
Wow! That game of Nattyholic was intense! My opponent died!
