A person who has a visible brown ring of dirt, grease, and other refuse on their neck. Used most often to identify the foulest of gamers or those individuals who believe that excelling in games such as Magic the Gathering, Dungeons and Dragons, or World of Warcraft is a license to forgo basic sanitation.
It is helpful to be able to identify Brown Necks at a distance as they are usually accompanied an overwhelming smell.
Brown Necks should not be confused with those gamers that enjoy games but maintain the social awerness to shower at least once a week.
I was going to ride the T into work today but the train was loaded with Brown Necks heading to Anime Boston. Gathered together the smell had become overpowering and some small children were on the verge of fainting. I decided to walk instead.
