The "That's what I'm talking about" meme originates from a viral video posted on December 4, 2018, by YouTuber T M. In the video, a Black man excitedly yells in a bedroom, saying, "That's what I'm talking about! That's why he's the MVP! That's why he's the GOAT; the GOAT!" His intense enthusiasm and body shake as he says "the GOAT" (meaning Greatest of All Time) made the clip popular. The video was presumably taken from Snapchat and gained over a million views in four years. The meme started to be used as a reaction video around the early 2020s and became widely popular on TikTok around 2022. It often appears in trends where people hype up someone as "the GOAT" or celebrate moments of approval and hype. It is closely tied to other meme trends such as the "City Boy" trend and the "Ranking Every X" trend. The phrase "That's what I'm talking about" from this video emphasizes excitement and approval and has become a meme to express strong agreement or enthusiasm for something.
