BON PLAN DE FOU— ORIGIN, MEANING & USAGE

bon plan de fou French informal expression for a very good tip or deal: « bon plan » (a good deal, a useful tip) with the intensifier « de fou », which means « really » or « a lot ». It is used when sharing promo codes, bargains, cheap trips or handy finds, and the verlan variant « de ouf » gives « bon plan de ouf ».

Origin:Wiktionnaire defines « de fou » as an informal adjectival locution meaning « really, very much », built from « de » and « fou », with the verlan variant « de ouf » and synonyms « de dingue » and « de malade », and it cites a 2020 tweet using it. The pairing with « bon plan » follows from that intensifier; no dated source found yet for « bon plan de fou » as a fixed phrase.
