Just This Once Meme

"Just This Once" is a meme from Jujutsu Kaisen featuring Yuta Okkotsu raising his finger and saying, “Just this once.” It originally referred to Yuta using his full power for a single fight, but fans later turned it into a reaction meme. The meme is often used when someone decides to do something unusual, break a rule, or make a rare exception. In 2026, it became popular in fandom memes, especially alongside the Lesbian Space Princess Fandom War trend, where different fandoms united “just this once” for a common joke.
