long green

またRaymond Chandlerの作品を読むことにしました。今度の小説はTrouble is My Businessの題が付いています。
"Then listen, Philip. I was in the Social Register once. My family were nice people. Old man Jeeter ruined my father- all proper and legitimate, the way that kind of heel ruins people-but he ruined him, and my father committed suicide, and my mother died and I've got a kid sister back East in school and perhaps I'm not too damn particular how I get the money to take care of her. And maybe I'm going to take care of old Jeeter one of these days, too-even if I have to marry his son to do it."
"Stepson, adopted son," I said. "No relation at all."
"It'll hurt him just as hard, brother. And the boy will have plenty of the long green in a couple of years. I could do worse-even if he does drink too much."
"You wouldn't say that in front of him, lady."
"long green" が分からないので辞書を引きます。
・Merriam-Webster's Online Dictionary: (slang) money: Where did he get the long green to afford wheels like that?
・Urban Dictionary: term meaning large amounts of money: I hear that hott chick from high school is making long green as a pornstar.
そう言えば "greenback" が１ドル紙幣の意味があったので、"long green" はスラングでも覚えられそうです。
