The clip comes from Dungeon Crawler Carl, the LitRPG series by Matt Dinniman about Carl and his ex-girlfriend's cat Princess Donut surviving a deadly alien dungeon crawl. Donut quickly became a fan favourite for her diva attitude and reckless choices, which constantly provoke Carl's exasperated catchphrase. The audiobooks helped spread the line beyond readers, turning short shouts like this into shareable reactions among fans. It is now used online whenever someone needs a funny, instantly recognisable expression of disbelief at a partner's chaos.
