2.
A word form MMORPGs, specifically the ones where enemies drop items to sell instead of just gold.
It means someone who picks up all the items he/she possibly can, no mater how lame and low sell price they may be.

Assassin Cross: hey dude why did you leave all those items laying there.
Lord Knight: Why not, they sell for almost nothing.
Assassin Cross: Yeah but it is still enough to make me want to pick it all up (picks up all the crappy items).
Lord Knight: God dammit I have an item whore in my party.
