Rizz emerged as Gen Z slang for romantic charm and was popularised in 2021 and 2022 by Twitch streamer Kai Cenat and his friends before exploding on TikTok. Adding W, short for win, turned it into quick praise for a successful flirt or confident move, while L rizz became the opposite insult. The drawn-out W Rizz clip spread through edits, duets and gaming streams as a reusable reaction, and it remains popular because the phrase is instantly understood even without context, letting creators label a moment smooth or cringe in under a second.
