The line comes from Joker, released in 2019, where Arthur Fleck, played by Joaquin Phoenix, confronts talk show host Murray Franklin, played by Robert De Niro. Fleck repeats the claim that comedy is subjective while challenging how Murray and the audience judge him. Clips of the exchange spread online as a reaction to debates about offensive jokes, standup sets and memes, because the wording sums up a familiar argument in a few seconds. It remains popular in edits where humor becomes the subject of the argument itself.
