Chicago Bank Roll 

It's a term used about how you hold your money. Some think that its all singles with a twenty on the outside. But, original it's was used for when you are in public. People can't see if your ballin, so you put the big bills in the middle and you work outward.

That kid is smart carrying that Chicago Bank Roll.
