“Balance ton quoi” (expose your what) is Angèle's 2019 satire of everyday sexism. The title plays on #BalanceTonPorc — “expose your pig” — the French version of the #MeToo movement, swapping the insult for a playful “quoi” (what). She mocks the men who complain they can't flirt anymore, and calls for respect, with a big sunny smile.
The video, a parody of a training course for men, made the point even sharper, and the song became an anthem for a generation of young French and Belgian women.
“Balancer” is a great slang verb: to throw, but also to snitch or to expose. The song is full of light irony, which makes it ideal once you're past the basics.
