Anuel AA, the Puerto Rican Latin trap artist, made brrr one of his most recognisable vocal trademarks, using the rolling sound as an ad-lib across his songs and social media posts. Fans began clipping the short burst and sharing it on its own, and it quickly spread through meme pages, edits and reaction videos as shorthand for cold, confident energy. Because it needs no translation and lasts less than a second, it works in almost any language and format, which is why it remains a go-to punchline for creators long after its first appearances in his music.
