quicko: bells on

I feel like it's taken me a bit longer than necessary to recognize this as an Australian/British expression, but it's really rather prevalent here:  "I'll be there with bells on."  It's in reply to an invitation -- generally to a party -- and I think is fairly understandable to Americans, just not something we'd think to say, unless of course we were ride-a-cock-horsing to Banbury Cross.
