Is it a common English phrase? I can’t find it in any English dictionary, and the wiktionary page has no listing for it under English, only in French. On the other hand the phrase “en masse” with a similar meaning shows up in dictionaries and the wiktionary page lists it under English.
Unless it’s quite a recent borrowing I’m thinking OP got the two mixed up, or is maybe from an area with enough French speakers that it seems common.
