Let Him Cook (and its variation Let That Boy Cook) is a slang-heavy meme rooted in hip-hop culture, specifically popularized by the rapper Lil B, also known as The BasedGod. The phrase serves as a metaphorical request to give someone the space and time to execute their vision or talent, even if their initial actions appear questionable or chaotic. It gained massive mainstream popularity on social media platforms like Twitter and TikTok around 2022, often applied to athletes, gamers, or public figures making a bold move. The meme captures the anticipation of waiting for a payoff, transitioning from skepticism to total support as the 'cooking' process unfolds and the final result is revealed.
