The phrase is attributed to former Brazilian president Jair Bolsonaro, and it translates from Portuguese as they are useful idiots, a familiar political insult for people seen as advancing a cause without understanding it. Circulated as a short standalone clip, it gained traction in Brazilian political meme culture, where brief audio bites are reused to comment on debates, elections, and partisan arguments online. Its staying power comes from its bluntness and brevity, allowing creators to attach a recognisable voice and a clear judgement to almost any moment of perceived political naivety.
