(acronym cqfd, but rarely used) : an offensive Quebec French phrase, which translated to English literally means an oafish, boorish, clumsy person who spectacularly fails at everything they do
(scene from Harry Potter and The Chamber of Secrets):

diary-released Tom Riddle : Harry, let me take you back in time, and show you who really opened The Chamber of Secrets the first time around.

Harry : who was he?

Tom Riddle: i am sure you would recognize him as Hagrid.

Harry: are you serious?Hagrid? But please don't qualify him as a con qui fail d'aplomb
