“Vai dar namoro” is a well-known Brazilian TV catchphrase that became a reaction sound in memes, especially in clips about flirting, dating and obvious romantic tension. Online, the stretched “uiii” before the line helped the audio spread because it is instantly recognizable and easy to drop into short edits. The clip remains popular in Portuguese-speaking meme culture because it communicates the whole joke in under two seconds: everybody watching can tell a couple is about to happen.
