phrase Extremely common #71
wouldn't have Informal spoken/written French for n'aurais pas, with ne dropped. aurais is the conditional form of avoir used with je or tu, so the full meaning depends on the subject: 'I wouldn't have' or 'you wouldn't have'. In questions like Tu aurais pas... ?, it can sound softer, like 'wouldn't you happen to have...?'
