Rarity is the fashion-obsessed unicorn from My Little Pony: Friendship is Magic, the animated series that ran from 2010 to 2019 and built a large online fandom. Her exaggerated elegance and horror of mess made lines like this one a natural reaction meme, quoted whenever something glamorous meets something filthy. The clip circulates in brony edits, gaming streams and TikTok videos as shorthand for high-maintenance drama, and it endures because the delivery is so theatrically over the top that it stays funny years after the show ended.
