The 'asdf' meme originates from the 'asdfmovie' series created by Thomas 'TomSka' Ridgewell, which debuted on YouTube in 2008. Characterized by its extremely minimalist stick figure animation and rapid-fire, non-sequitur comedy, the series became a cornerstone of early internet culture. Iconic sketches like the 'I Like Trains' kid, the 'Muffin Time' song, and 'Everybody Do The Flop' have been parodied and memed millions of times. The 'asdf' aesthetic represents a specific era of web animation where randomness and deadpan delivery reigned supreme, allowing creators to apply that same chaotic energy to their own custom captions.
