A person who thinks the manga One Piece is the best thing ever written despite not reading or watching anything else but One Piece and maybe some other mainstream shit.

You can mainly find them on twitter and reddit. They usually use words like "GODA" and "One Piece is King".
They also appear to deeply care about sales but only when One Piece is at the number 1 spot. When the number 1 spot is taken from One Piece you can find them saying that sales don't matter but instead quality does but, unfortunately, they don't realize that the quality of One Piece isn't as good as they think it is, so while that statement is true, it's true not in the way they would like it to be.
Hey do you have any great manga I can read?

Read One Piece, it's the best thing ever, 10/10, you won't regret it.
