Online, the phrase has become shorthand for an understatement, used when a reaction is obviously stronger than the words suggest. Short form editors pair it with reaction faces, gaming fails and reality clips, often alongside an awkward cricket moment to stretch the silence. It spread through meme pages and short video feeds as a reusable caption and audio cue, rather than as a line tied to one clear source, and it stays popular because almost any failed joke, rejection or blunt comment can fit the same setup perfectly well.
