The phrase comes from Czesio, one of the main young characters in the Polish animated comedy series Włatcy móch, where his childlike voice and mischievous delivery made many of his lines easy to lift as short clips. Fans began sharing the goodbye as a standalone reaction sound in Polish meme edits and video compilations, where its playful tone worked as a dismissive send-off. It has stayed popular because it is instantly recognisable to viewers familiar with the show, yet clear enough as a simple taunting goodbye for new listeners too.
