4rry
A disparaging term for people who prefer the current 4th edition of dungeons and dragons to 3rd edition, which was current from 2001-2008. It is primarily used on the /tg/ board on 4chan, which is the board that is most related to the game. It is meant to sound similar to "furry," since furries are generally disliked on 4chan. Part of this comes from the inclusion of Dragonborn, a sort of antropomorphic dragon, as a core playable race.
