The clip comes from a Spanish-language YouTube Poop edit titled Dross Asiste a las Clases De Don Ramón, which places the YouTuber Dross in the classroom of Don Ramón, the well-known character from El Chavo del Ocho. In that classroom setting, a grade of minus ten becomes an exaggerated joke about failing completely, rather than just scoring badly. Shared as a short standalone sound, it spread through meme edits and soundboards because the phrase is instantly understood even without the original video, and it gives creators a quick, harsh verdict for any failed attempt.
