The Godfather
The original quote, with slang
Jack Woltz: Now you listen to me, you smooth talking son of a bitch. Let me lay it on the line for you and your boss, whoever he is. Johnny Fontane will never get that movie. I don't care how many dago guinea wop greaseball goombahs come out of the woodwork.
What does it mean?
Jack Woltz: Now you listen to me, you horrible man who tries to talk in a pleasing way. Let me explain this clearly for you and your boss, whoever he is. Johnny Fontane will never get that movie deal. I don't care how many worthless Italian* mafia-connected men appear to convince me.
*dago, guinea, wop and greaseball are all derogatory terms for Italians

Johnny Fontane: Oh, Godfather, I don't know what to do. I don't know what to do.
Don Corleone:You can act like a man! What's the matter with you? Is this how you turned out? A Hollywood finocchio that cries like a woman.

Johnny Fontane: Oh, Godfather, I don't know what to do. I don't know what to do.
Don Corleone:You can act like a man! What is wrong with you? Is this what you have become as an adult? A Hollywood gay man that cries like a woman.
The original quote, with slang
Sonny: Hey, whadaya gonna do, nice college boy, eh? Didn't want to get mixed up in the Family business, huh? Now you wanna gun down a police captain. Why? Because he slapped ya in the face a little bit? Hah? What do you think this is — the Army, where you shoot 'em a mile away? You've gotta get up close like this and bada-bing. You blow their brains all over your nice Ivy League suit.
What does it mean?
Sonny: Hey, what are you going to do, nice college boy? You didn't want to get involved in the family's mafia business, did you? Now you want to shoot and kill a police captain. Why? Because he slapped you in the face a little bit? What are you thinking? What do you think this is? Do you think it's like the Army, where you shoot them from a long distance? You've got to get very close like this and then you shoot them in the head. When that happens, their brains will make your nice Ivy League* style suit all dirty.
*Ivy League refers to eight old, exclusive and expensive universities :Harvard, Yale, Dartmouth, Cornell, Brown, Columbia, Princeton and the University of Pennsylvania (so-called because they have ivy plants growing on the sides of their brick buildings). In the movie, Sonny is addressing his more educated brother Michael, who went to Darthmouth while Sonny became part of the Corleone crime family.
