Buckley's and none

Little to no chance of something. It is likely a pun on the name "Buckley & Nunn," a department store that was founded in 1851. It is often preceded by "two chances" in some form or another. Primarily heard in Australia. A: "Do you think she'd go out on a date with me?" B: "I'd say you have two chances—Buckley's and none." Oh please, you've got Buckley's and none of this working out. Mum is definitely going to catch you! If you've already been fighting with the city for that permit for a year, my guess is that you have Buckley's and none of ever getting it.
