Widely used in MMORPG Games (Mass Multi-player Online Role-playing Game). It's used to define a game channel which PK (Player Kill) is prohibited and therefore players can play in peace without unreasonable interferences from other players. The word "Carebear" is used because the players playing in those channels are deemed by other players to be cowards and wanted to be protected rather than facing the harsh world of reality where there's bound to be PK.
If you do not want to be PKed for no reasons by some lunatics, especially the mapletards, please switch your game channel to the Carebear Channel.
