Toge Inumaki is a supporting character in Gege Akutami's Jujutsu Kaisen manga and its 2020 anime adaptation. To avoid accidentally cursing others with his voice, he limits himself to onigiri ingredient names, a quirk fans instantly adopted as in-jokes and reaction sounds. Tuna mayo became one of his most quoted phrases, shared in short clips, edits and soundboards alongside salmon and bonito flakes. Its lasting appeal comes from how much personality and meaning regular viewers read into just two calmly spoken words.
