e-bushido

A player of a (usually online) video game, who will fight to the death no matter how overwhelming the odds are against them. Even when defeat is certain, players with e-bushido will never quit the game before they have been totally defeated.

Derived from the Japanese "Bushido" code, which forbade samurai from surrendering.

Player: He's already lost, why doesn't he quit?
Other player: He is e-bushido, he wont give up until he has lost
Player: Wow he has no life
