Casser les pieds à quelqu'un

Meaning: To annoy or bore someone greatly.

Literally: To break someone's feet

Example: “Tu me casses les pieds avec tes questions, laisse-moi travailler !” — You're driving me crazy with your questions; let me work!

English equivalent: To be a pain in the neck

Origin: Pairing casser with a body part to mean annoying someone goes back to the start of the 12th century, but feet only enter the picture at the end of the 19th, and by way of a detour through ears: casser les oreilles (to deafen someone with noise or chatter) comes first, and casser les pieds takes over the same job. Walking was simply how people got anywhere, so sore or damaged feet meant every errand became a small ordeal — which is exactly the friction an insistent, tiresome person creates without laying a hand on you.
