The 'Mistah Merriku' or 'Bugs in Anusu' meme stems from a video of former Pokémon director Junichi Masuda during a promotional event. Due to his specific pronunciation and the audio quality, internet users began jokingly misinterpreting his Japanese introduction as bizarre English phrases. This phenomenon birthed the 'Masuda-posting' subculture, where fans use his image and audio for absurdist humor and Pokémon-themed shitposts. Often accompanied by high-energy music or distorted visuals, the meme is a staple on platforms like Twitter and Reddit within the Pokémon community, serving as a chaotic way to reference the franchise's development history or simply to share surreal humor.
