Carebear

MMO slang used to label individual/groups of players who detest and avoid PvP or potential griefing in online games. Carebears might be frowned upon by experienced players, not necessarily due to their cowardice and aversion to competition, but because of how they deal with griefers by reporting them to moderators instead of allying up with other players. They are the bane of pros trying to make "Evil" characters in MMORPGs.
Carebears primarily play games with mechanics/server plugins that prevent stealing/killing other players (Safe/Policed Zones, limited-to-none player loot, arena-only PVP, those shitty Minecraft servers with Anti-Grief plugins, etc.) and will complain on forums about PKers, only to be told to git gud.
Most carebears are lowbie solo players, but there also exist PvP Carebears that exploit safe zones to avoid a fair death.

And no, not wanting to get randomly killed by a lvl 70 permavirgin despite your items being useless to him, or have the spawn surrounded by a gang of P2W kids does not make you a carebear.

"Those carebears could simply hire some lvl. 60 paladin to drive away that guy on a killing spree in the town... But naah, they have to ride admin cock and report them instead."
