The 'What's Poppin' meme gained massive traction following the 2020 release of Jack Harlow's breakout single of the same name. While the phrase itself is a common greeting, the meme typically captures the energy of making a grand entrance, flexing a new achievement, or ironically showing up to a chaotic situation. On platforms like TikTok and Twitter, users pair the catchy lyrics with videos of unexpected arrivals or major life updates. It has evolved into a versatile template for anyone looking to announce their presence with a mix of swagger and humor, making it a staple for modern social media commentary.
