Common term for gamers who uncontrollably loot all obtainable stuff in a game, seen in genres like RPG and MMORPG.
Most of the time this loot-addiction is a bad habit which sometimes makes both singleplayer and multiplayer games unplayable due the fact of being overencumbered.
(Player 2 shot down an enemy)
Player 1:"Nice shot, let's go to the hiding spot again."
Player 2:"Wait, first I need to loot him, I can use this, and that.. Oh his fancy roller skates I can use too."
(Enemies are approaching)
Player 1:"We're running out of time, quick get back in the hiding spot!"
Player 2:"Wait.. I'm overencumbered."
Player 1:"God****!! Crazy Loot-Addict!!"
