Meta Rat

A "Meta Rat" is a person who uses only the most overpowered and disgustingly powerful weapons in a game and refuses to even consider using anything else.

An example, people who decide that if 'weapon x' will destroy my opponent and leave them without a single chance of hurting my character with 'weapon b through z' it must be the only weapon I use.

A prime specimen, Roze skins in CoD MW19, smgs in siege and the charged shotgun in Fortnite.

Person A: look at this CUNT! Using FFAR, dirty bastard!

Person B: he's sweating and he's a Roze. Fucking Meta Rat!
