The Jon Hamm Dancing meme, often paired with the song 'Turn the Lights Off' by Tally Hall, originates from a high-energy scene in the 2017 film Baby Driver. In the clip, Hamm’s character Buddy displays a charismatic and slightly manic intensity while moving to the music in a club setting. The meme gained massive traction on TikTok and social media as a way to represent a sudden shift in personality or a 'beast mode' being activated. It is frequently used to illustrate scenarios where someone goes from being calm to completely locked in, or simply to celebrate a song that hits different when the lights go down.
