Hi, everybody! An English friend of mine has written a short-story and sent it for me to have a look at it. There's a sentence that puzzles me, and I'd like to be able to understand it without having to ask him. It's a boy-meets-girl story in a library. The girl is rather bookish, the boy isn't, but he pretends to be, because he likes the girl. They engage in conversation and she says that she'd give him some stories by Scott Fitzgerald, her favourite author, for him to read. Later on, they make an appointment to comment the stories over a coffee. They're talking about the stories, and then he says: "I've just thought of something terrible that you could say: 'Scott Fitzgerald will get you nowhere, boom boom' ". Could anybody help me understand the meaning of boom boom here? Thanks in advance!
