As a Spanish-language reaction sound, 'Esto no es llorar' circulates mainly in short-form edits and meme compilations, where the phrase itself does the comic work. Because the words are simple and instantly understood by Spanish speakers, creators can drop it into almost any tearful or melodramatic moment without needing extra context. Its popularity comes from that reusable denial: the speaker claims composure while the audience can see the opposite, a pattern that fits reaction videos, parody edits and light-hearted roasts of friends.
