The 'Rack City' meme originates from the 2011 hit single by American rapper Tyga, which became a cultural phenomenon due to its infectious DJ Mustard production and repetitive hook. In the world of memes, 'Rack City' transitioned from a club anthem to a digital shorthand for wealth and 'flexing.' It gained significant traction on platforms like Vine and later TikTok, where users synced the heavy bass drop to humorous reveals of cash, luxury items, or ironic situations where someone feels rich. The meme captures the essence of early 2010s hip-hop bravado and is frequently used to highlight financial wins or mock excessive displays of money.
