Rizz is Gen Z slang shortened from charisma, describing someone's ability to attract or charm another person. The term spread widely through Twitch streams and TikTok in the early 2020s and was named Oxford Word of the Year in 2023. As the word became a meme, creators began tagging confident or cringey flirting clips with a rizz sound effect to mark the moment. It remains popular because it works both sincerely for smooth moves and ironically for failed ones.
