The phrase "That's what she said" existed long before meme culture, but it became especially well known through Michael Scott on the US version of The Office in the 2000s. Online, the short audio version spread as a reaction clip for double entendres, awkward slips and intentionally childish edits. It remains popular because the setup is everywhere: any sentence with unfortunate wording can trigger the joke. On soundboards and short videos, creators use it as a fast punchline much like awkward cricket or chipmunk laugh.
