Clash Royale is Supercell's mobile strategy game, released in 2016, where players deploy cards including the Poison spell to damage troops inside a small area over time. The Spanish word veneno simply means poison, which is why Spanish-speaking players often label the clip that way. The sound has circulated on soundboards and in short gaming edits because it is short, instantly tied to the game, and useful beyond gameplay as a quick audio cue for toxicity, bad decisions or a plan going wrong.
