Formidable means "wonderful" or "great", but the genius of this song is in its wordplay. Stromae masterfully breaks the word in two to create a hidden, opposite meaning.
He sings, "Tu étais formidable, j'étais fort minable" (You were wonderful, I was very pathetic). This clever pun, where the single word formidable sounds just like the phrase fort minable, captures the entire song's theme of feeling worthless after a relationship that once felt so great.
Formidable drops us onto a rainy Brussels sidewalk where Stromae, half-drunk and heartbroken, rambles at strangers about a love that has crashed and burned. With every slurred “Tu étais formidable, j'étais fort minable,” he flips between praising his ex and trash-talking himself, turning the city into a stage for raw, embarrassing honesty. His one-man monologue swerves from flirting with a passer-by to mocking a married man, to lecturing a kid about grown-up hypocrisy, showing how alcohol can loosen the tongue and reveal messy truths hidden beneath everyday politeness.
Behind the tipsy theatrics lies a sharp critique of romance and societal expectations. Stromae pokes holes in the fairy-tale of everlasting love, hinting that rings can rust, parents can cheat, and even the cutest “baby monkey” may grow up to repeat the cycle. By contrasting formidable (amazing) with fort minable (utterly pathetic), he reminds us that greatness and weakness often coexist in the same heartbeat. The song is a catchy, hip-hop confession that laughs, cries, and staggers all at once—inviting listeners to recognize their own vulnerable moments and maybe dance them off.
