Padoru Padoru grew out of the Fate/Grand Order fandom, where a festive parody of Jingle Bells featuring Nero Claudius turned the repeated word padoru into a Christmas catchphrase. The chant spread through YouTube edits, fan art and social posts, returning every December as a seasonal in-joke for anime fans. Triggered versions like this one came later, distorting the cheerful original into a loud reaction sound for edits that need instant chaos. Its mix of nostalgia, holiday timing and recognisable melody keeps it popular year after year.
