The phrase and guess what has long been used in everyday conversation as a playful way to introduce gossip, news or a twist, and that familiarity is exactly why it works so well as a short soundboard clip. Online, creators use it as a compact setup line in memes, reaction videos and short-form edits, where its teasing tone primes the audience for whatever comes next. Because the wording is simple and instantly understood, it travels easily across different kinds of content, from comedy sketches to storytime videos, and stays useful long after individual trends fade.
