Bakudeku combines the names Bakugo and Deku, the rival heroes Katsuki Bakugo and Izuku Midoriya from My Hero Academia, and the pairing has inspired a huge amount of fan art, edits and audio remixes online. This slime version does not come from an official episode scene, but from fandom and ASMR culture where satisfying squish sounds are looped under edits. It spread through short video platforms as a recognisable texture sound, and it remains popular because the pairing is well known and the slime audio works even without visuals.
