A basement dwelling PvP gamer that insistently plays the most optimal characters, strategies or buys the best items at every opportunity. They *have* to win by any means necessary.
This behaviour is concomitantly linked with a lack of playing ability, which is observed whenever they are forced to play anything but meta-picks.
Meta-goblins act as a source of frustration for other players, as they often breach PvP etiquette within the community of said game.
"Look at this meta-goblin, he only plays Bellona in duel with death's embrace."
*Looks at his match history on SmiteGuru*
"Oh, and anytime Bellona gets banned they lose because they're incapable of playing any other character".
