The phrase works online because it is a common everyday question that instantly signals doubt without needing context. Short reaction clips like this spread through soundboards, meme edits and messaging apps, where a familiar line can be reused for many different setups. Its popularity comes from timing rather than a specific scene, the brief delivery fits chats, livestreams and short videos equally well. Creators keep returning to it for moments when something sounds off, unclear or unintentionally funny, and a direct question says more than an explanation.
