The clip comes from television advertising for Bagel Bites, the bite sized pizza snacks sold as a quick after school treat. In the commercial the word pizza is sung with huge enthusiasm as part of the catchy jingle that listed pizza at any time of day. Online the isolated yell was separated from the song and reused as a standalone reaction, shared on soundboards and in edits where an overblown food announcement is funnier than a normal voiceover.
