C’est une dinguerie means “it’s insane,” and these days usually in a good way: an amazing cake, a great goal, a wild video. It comes from dingue (“crazy”) plus the noun ending -erie. The word used to mean plain madness, but the praise sense spread so quickly on social media that the 2026 Petit Robert dictionary added it. It’s casual and young-sounding.
You’ll hear it as a reaction on its own (une dinguerie !) or in a sentence, as here: c’est une dinguerie à tester d’urgence, “it’s insane, you have to try it right away.” Older relatives may still read it as “madness,” so context matters. Neighbouring words include c’est dingue (“it’s crazy”) and c’est de la folie (“it’s madness”), which can also be positive.
