Dictionaries are always adding new definitions, but these days, social media has a big impact on which words get chosen—and how quickly. Case in point: In December, the publishers of the Oxford English Dictionary crowned “rizz” as the 2023 Word of the Year, beating out contenders such as “situationship” and “de-influencing.” Rizz—which is short for “charisma” and is slang for “style, charm, or attractiveness”—first emerged out of internet and gaming culture when YouTube and Twitch streamer Kai Cenat popularized it by posting “rizz tips.” It then went viral last June after actor Tom Holland said in an interview, “I have no rizz whatsoever. I have limited rizz.” That spawned a crush of memes, and overall usage of the word surged. Social media has exponentially increased the pace of language change, says Casper Grathwohl, president of Oxford Languages. Plus, he adds, the word simply has . . . rizz. “One of the reasons it’s moving from being a niche social media phrase into the mainstream is it’s just fun to say,” Grathwohl says. “When it comes off your tongue, there’s a little bit of joy that comes with it.”
