This is a great list containing slang terms which are commonly used in gambling that newbies should know before continuing their gambling journey.
good that you brought this out here , because newbies eve me have no complete idea about those slang word till now(but I knew most of them right there) so this will help us understanding specially when in terms of using groups.
But you think newbies are going to learn that. I think it's normal for them to learn the terms like everyone else, at first they sound strange to you, and when you hear them repeatedly in context you realise what they mean. Or if you hear it and have doubts you look it up on the internet. I think that few people will be those who have no idea of these terms and learn them by reading this thread.
I think the OP's compilation is more useful for those who are not newbies, but who have already got into gambling, have some idea but have doubts about other terms.
