Someone who plays a multiplayer video game and refuses to use any weapons/characters/skills that aren't considered "meta."
Although someone who uses the meta can be someone who simply enjoys using the most reliable tactics available, "Metaslave" is used to describe someone who sees anyone who doesn't use the meta as an idiot or noob and may even berate those who refuse to comply with their demands.
Originated from League of Legends to describe someone who uses an overpowered champion in order to climb up the competitive ranks.
"Hey, why did Todd get banned from the community server?"

"Metafucker", derived from the term "Meta" (meaning: Most Effective Tactic Available), is a player in an mmo who focuses too much on what is the "best" tactic or build to use in a game so much to the point where they are willing to drop their pants and fuck it. They are usually elitists who want to be the most over powered players while simultaneously looking down on those who go for different tactics or builds, even if they are just as good.
Metafucker: "This new set that just got released last patch is the new meta."
Player: "Yeah it looks nice but my current set is just as good."
Metafucker: "Lmao, no it's not youstupid retard. This is the new best set, keep up."
Player: "K. Metafucker."
