Need help with a little bro nickname

[jdel]

Sorry guys, I'm new and this is probably a bad topic for a thread, but I'm REALLY uncreative haha and I want my little bro to have a good nickname - one people will actually use. Anyone think they can help me out?

I can't think of a name, but I know two themes that would work well:

The kid is money obsessed - Finance major, stocks, the whole nine yards. He's all about workin hard and gettin rich. Here's a story to demonstrate - When I asked him what he wanted our brother colors to be (something my chapter does, idk if other people do that too, our family tree has its own set of colors and I'm starting my own tree) and he said green shirt with gold letters - the colors of cash and gold lol.

Alternatively, the kid is really intercultural. Italian/Peruvian mix who grew up in Belgium and now lives in NYC. So something along that could be cool too, just don't get racist.

Anyone who has some good ideas, I would really appreciate it! I just don't want to think of a really bad nickname that never gets used haha
