Ryusei Shidou is the unpredictable striker from Blue Lock, the football manga by Muneyuki Kaneshiro and Yusuke Nomura that became an anime in 2022. His wild playing style and theatrical lines made his English dub moments easy to clip and share. Kablowey spread through anime edits, football fan videos and soundboards as a short burst for goals, explosions and dramatic entrances. Fans keep using it because the word itself sounds like an impact, even without the scene, and Shidou's reputation gives the shout extra menace and humour.
