That's What She Said is an old innuendo punchline that became a mainstream meme after Michael Scott repeated it constantly in the US version of The Office, which ran from 2005 to 2013. Steve Carell's character used it after almost any innocent statement, turning it into the show's signature running gag. Clips and soundboard versions spread through early YouTube, forums and later short form video, where the isolated line became shorthand for spotting a double meaning without needing the original scene for context.
