Marselo is a surreal internet character originating from the Spanish-speaking meme community, specifically gaining massive popularity in late 2019 and early 2020. The character is a low-resolution, gray 3D model of a humanoid figure, often paired with the rhyming phrase 'Agáchate y conócelo' (Duck down and meet him). It evolved into a staple of shitposting culture due to its bizarre aesthetic and nonsensical nature. While its exact origins are linked to early 3D stock assets, its transformation into a viral sensation highlights the internet's love for low-quality, abstract humor that transcends linguistic barriers.
