But since the government was fooled and put out a bounty for Sogeking instead of him, and because Luffy fell for it, people like to pretend that Sogeking is a mysterious character that isn't just Usopp's alter ego.
So pretty much the same thing as the Masked Royal meme. Fans also tried the same shit with the Defenders of Kalos last gen, though it was an even less popular meme back then.
