The line comes from RWBY Chibi, Rooster Teeth's short-form comedy spin-off of RWBY, specifically season two, episode one, where Penny appears alongside the main cast in a lighter, joke-driven format. Penny, an android created in the RWBY universe, often misunderstands human habits, and calling people meatpersons fits that running joke about her literal way of seeing the world. Fans clipped the moment for soundboards and edits because it is short, quotable and instantly recognisable to RWBY viewers, and it continues to circulate as a playful reaction sound rather than a dramatic quote.
