I'm trying to research accurate "street" terminology for a three shell game routine I'm working on. I'm thinking specifically of the version using bottle caps and a bit of foam from a mattress or pillow, as often seen on the streets of New York. Is there a name for this other than the "three shell game"? In addition, I know, of course, about "punters" and "shills", but are there are other, possibly more current terms in use? Any help from those knowledgeable about this world would be greatly appreciated.
