As a French expression, tous des nuls is a familiar insult used in everyday speech to call a whole group useless or hopeless, which makes it instantly recognisable to French-speaking listeners even without context. Online, short voice clips like this one circulate as reaction sounds because they carry attitude in under seven seconds and need no translation for the intended audience. It works best as a punchline rather than a conversation, which is why creators keep reusing it for fails, debates and playful teasing between friends.
