Jildy jildy

Hello. Great site!

Clicked on the chop chop entry then looked about for another phrase my grandfather used to use - often directly after chop chop - jildy jildy...
Didn't find it on your site, but a search finds

en.wiktionary.org/ wiki/jildy

Seems to fit as my grandfather was a merchant seaman during WW2 and I know he visited India and China, but I've never heard anyone else use that phrase!
