Dare is a slang term in French, particularly popular in youth culture, meaning 'cool' or 'awesome'. It's an interesting word because it's not standard French and adds a modern, informal flavor to the lyrics.
In the song, Aya Nakamura uses it to describe her lover: "Mon chéri, il gère le biz' et c'est dare" (My darling, he handles business and he's cool/awesome). This word choice immediately signals a contemporary and street-smart vibe, making it enticing for learners interested in modern French slang.
"Mon chéri" is Aya Nakamura's take on falling for someone you know is trouble. She sings about a man who runs his business smoothly, moves with confidence, and never stops wanting to whisk her away, but that same charm is exactly what wears her down.
The chorus admits the whole thing plainly: he tempted her, and she fell. She had him in her sights for a long time before giving in, and now the two of them are simply "us," money and Louboutins included. There is no pretending this is a calm, easy love. It is addictive, a little reckless, and impossible to walk away from, which is the point of the title itself: he is her darling even when he is also her weakness.
