I am watching Martin Scorcese's movie Casino (1995) and there is lot of idioms. I am not native english speaker so I am searching for the meaning of quotes I didnt know already. I found meaning of most of them but I cant find meaning of the last two sentences in this one (in bold):
"The little guy. He's half in the bag, and nobody told him he was eighty-sixed from the joint, so we all turned our heads and made out like we didn't know who he was. He's over at the twenty-one table with his nose wide open. He took the money out of his own kick. His nose is open for about ten thousand."
I thought "nose wide open" has something to do with using cocaine but it doesnt make much sense. Thanks for explanation of the meaning.
