The exact source recording behind dekuracisme is not clearly documented, so the clip is best understood through its online life as a soundboard meme. Its name links it to Deku, the nickname of Izuku Midoriya from My Hero Academia, one of the most edited anime series in meme culture. Short, out-of-context anime voice clips like this spread through TikTok edits, Discord servers and reaction videos, where recognisability matters more than context. It remains in use because it is instant, portable and works even for viewers who do not know the original scene.
