Role Play Nerd. Worse than regular nerds. These include but are not limited to those who dress up while playing WoW, DnD, AoC, Aion and Magic: The Gathering. These people also refuse to wear/use certain items in game because "it would break the Role Play n00b."

Nerd: Why not?
RP Nerd: I'm a female.
Nerd: Not in real life.
RP Nerd: Can't break the role play n00b.
