What's a phrase you misinterpreted the meaning of for the longest time? - tchncs

I’ve seen people using “that’s what she said” in a very serious setting, as a way to say “good point/touché”. They had no idea it was from the Office.

“That’s what she said” long predates the office. I feel like it was used in SNL in the 80’s.

That’s what she said appears in print as early as Edmond Addeo and Robert Burger’s 1973 book EgoSpeak: Why No One Listens to You: “The cheapest shot of all, of course, is the ancient one-liner, ‘That’s what she said.’ This reply can be used after virtually any remark, however innocent, and the speaker can summon up some hint of double-entendre.”

As the actress said to the Bishop.
