Il est en cheville avec un revendeur marron

n. f.

1. (Underworld slang): Important 'contact', individual whose valuable assistance borders on complicity. (The expression être en cheville avec nearly always relates to associations of a dubious nature. Il est en cheville avec un revendeur marron: He's in cahoots with some sort of fence.)

2. Ne pas avoir mal aux chevilles (iron.): To be a glutton for compliments. (In the same way that the polishing of fingernails on one's clothing is deemed in 'body-language' to express self-satisfaction, for a Frenchman kicking his ankles translates appreciation at being showered with compliments.)
