Buckley's chance(redirected from Buckleys chance)
Little to no chance of something. Of uncertain origin, it is either a reference to "Buckley's and none" (a pun from the former department store Buckley's & Nunn), or to the escapades of the escaped colonial convict William Buckley. Primarily heard in Australia. I'd say you have Buckley's chance of getting that loan approved.
