Shaking my booty, apparently

This morning during a break, one of my students said ,''J'aime beaucoup votre déhanchement, Madame." I really like your.... I had never heard of déhancher or déhanchement. Given the fact that all the other students had rather vocal reactions to his comment, I was worried. I know that hanche is hip (the body part) so I was thinking hipness, but no, hip is only hip (cool) in English. Hippiness. God no, I'm no hippy. (Yes, of course, no friggin' offense to all the hippies out there. You're lovely people.) I sought help.

The secretary, who speaks English really well, reassured me. No, she said, it just means he likes the way you walk. Uh huh.

Husband put it differently.

During lunch, I asked him what déhancher means. He asked for the context. I gave it. He said, "It means you shake your ass when you walk."

Well I never.
