The clip comes from iReady, the online reading and maths programme used in many US classrooms, where the character Jake often reacts out loud during lessons. Students who grew up hearing that line began clipping it and sharing it outside school as a joke about being completely lost. It spread through short form video and classroom edit communities alongside other confused reaction sounds, because the short delivery fits almost any baffling statement. It remains popular as a clean, school sourced alternative to stronger shocked reactions.
