Jacksfilms, the YouTube comedy creator Jack Douglass, built a running bit around a strained Kermit the Frog impression, using the voice in sketches, YIAY episodes and reaction-style jokes. The clipped yay became a standalone reaction sound on soundboards because it captures his version of Kermit perfectly: earnest, nasal and slightly off-key. Fans reuse it across edits and streams as a quick shorthand for childlike excitement, often when the thing being celebrated does not deserve that much enthusiasm, which is exactly why the joke keeps spreading.
