It's pronounced "meta-four" (메타포 or メタフォー); the profile icon is a difficulty icon from the Pump It Up series. Sorry, I deleted Discord and I'm not going back on that.

I play a lot of games, but my favorites don't add to my Steam hour counts: Celeste I play on another version so I don't have to wait for Steam to open, and Pump It Up is an arcade game.
