Horder

[Little_Girl]

A member of The [Horde] (see also: [WoW], [World of Warcraft], [MMORPG]) who accumulates as many items as possible and never shares them, sells them, or uses them. They will cling selfishly to these items until they are no longer useful and expired from game play OR hoard things like cloth that could be used by the guild. This often results in creation of extra characters simply for bank tab space.
Literally, A Horde Hoarder.
