loot pig

A person usually found in an online multiplayer role-playing game, who wants nothing more than to have every item in the game regardless of the item's worth to their character.

Someone who wants all the group rewards for themselves.

Tactics employed by loot pigs vary from rolling 'need' on every item, rushing to be the first one to open every corpse/chest, and squealing like an actual pig when they don't get their way.

Willy is such a loot pig he stopped fighting when the encounter was nearly over, so he could be the first to hover his cursor over the dead mob.
