A temporary pseudo-anarchical state in which most official rules and regulations (i.e. laws) can be disregarded/ignored completely, without fear of capture and prosecution. Originated during heavy snowfall in small southern townships that contained an abundance of drunken, overgrown and overzealous youth.
Chip had just smashed a random car with snowballs, and then assaulted the driver immediately afterward. However, he wasn't worried; after all, it was snow rules.
