I found https://blogulblog.wordpress.com/z-postari-pe-alte-teme-ling... which lists it as coming from Romani. However, I find that a bit weird, as it's čor – hoț. The first letter being https://en.wikipedia.org/wiki/Voiceless_postalveolar_affrica...

So, yes, cioara could come from there, but not sure how you get from there to hot. And, DEX lists cioara as coming from the Albanian sorrë.
