MC Carol is a Brazilian funk artist whose blunt, funny lyrics about dating and relationships travel widely on Brazilian social media, and 'novinho interesseiro' is one of her most quoted lines. The two-second clip spread through short-form video apps, where creators began using it as a shorthand insult for an opportunistic younger admirer. Because it is so short, it works as a punchline tag on memes, edits and reaction videos, and it keeps circulating as long as dating jokes stay popular.
