The type of person who hates the massive multiplayer game "runescape" for no apparent reason commonly stating that the players have no lives.
It is common to expect a runescape hater in a forum to jump in a topic that lightly mentions it and reply saying the game is gay in most cases.
They are quite similar to anime haters.
"Runescape haters need to learn how to forget it even exists."
"Sure the community can be horrible at times, but it's no reason to go all "LOLZ ITS GHEY" like a runescape hater all the time"
A Runescape hater is a person who knows what they are talking about. They might say Runescapians, or runescape players have no life, because in most cases their life is runescape.
