Guaraná is a popular Brazilian soft drink made from the guaraná fruit, and the phrase toma um guaraná simply means take a guaraná. Online, the line circulates as a short, exaggerated audio meme, with the final syllable stretched for comic effect in the style of many Brazilian WhatsApp and soundboard clips. Its appeal comes from that contrast between an ordinary offer and an over-the-top delivery, which makes it easy to reuse across thirst jokes, party edits and reaction videos without needing context from a specific show or film.
