I wondered about the name. I guess I'm unfamiliar with a bunch of South Asian references, apparently it is Hindi and related to currency: https://en.wiktionary.org/wiki/%E0%A4%AA%E0%A5%88%E0%A4%B8%E...

I was perplexed a bit because paisa (like paisano, countryman) is also a word I hear a lot among Latin American immigrants in the US, seems like one of those things that can be taken offensively but I mostly seem to hear it as a term of endearment.
