The 'STFU' meme encompasses a wide variety of reaction images used to abruptly silence someone or express intense focus on something else, most notably music. One of the most iconic versions features Joji’s character 'Pink Guy' from the Filthy Frank show, while modern iterations often use the 'STFU I'm listening to' format to highlight niche songs or absurd audio clips. Serving as the ultimate conversational 'stop' button, it transitioned from toxic gaming lobbies to a playful way of expressing passion for specific media. It remains a staple in internet culture for its bluntness and high versatility in social media arguments and shitposting.
