The phrase comes from Brazilian Portuguese slang, where curto is an informal way of saying I like or I am into something, so não curto flor is a casual way to say flowers are not my thing. The clip circulates mainly as a short reaction sound on meme soundboards and in chat edits, detached from any single scene. Its appeal is the contrast between the ordinary topic and the firm tone, which lets users apply it to Valentine's posts, florist videos, allergy jokes and any moment needing a blunt no.
