The 'Mario Pissing' meme features a low-polygon 3D model of Mario, typically resembling his appearance from Super Mario 64, captured in the act of urinating. This image belongs to the broader 'cursed images' and 'shitposting' subcultures where iconic, wholesome characters are placed in crude or surreal situations. While the exact origin is often linked to early 2010s message boards and Garry's Mod renders, it saw a massive resurgence on platforms like Twitter and Reddit as a ultimate reaction image. It is most commonly used to express extreme disrespect or indifference toward a specific opinion, community, or individual, effectively 'pissing' on whatever the user finds objectionable or annoying.
