Okay... here's a scene. Clint is Walt... this is pretty much how the whole movie goes language wise...
EXT./INT. BARBERSHOP - DAY
Walt and Tao walk up to the barbershop.
WALT
You have to learn how guys talk.
Now watch how me and Martin communicate. We just throw it back and forth. You ready?
TAO
Sure.
WALT
Okay, let's go in.
Walt holds the door for Tao and they enter. The Barber has his feet up reading a Playboy.
BARBER
Oh great, a Pollack and a chink.
WALT
Afternoon, Martin, you dumb Italian prick.
BARBER
Walt, you cheap asshole, I should have known you'd come in, I was having such a pleasant day.
WALT
Why, did you jew some blind man out of a few bucks, give him the wrong change?
Walt and the Barber shake hands warmly. Tao is wideeyed.
BARBER
Who's the Nip?
WALT
This is Tao. He's a pussy kid who lives next door and I'm trying to man him up a little.
Walt points at Tao.
WALT
Did you see? That's how men talk to each other.
TAO
They do?
BARBER
What, do you have shit in your ears?
WALT
Okay. You go out, come back in and give it a try.
TAO
Come on, Walt.
WALT
I said go out there, come back in and talk to the barber like a man.
Do it.
Tao shrugs, goes outside, lets the door shut then comes back in. The Barber stands there with a sneer on his face.
TAO
Wus up, you old Italian prick?
The Barber levels a sawed-off SHOTGUN at Tao.
BARBER
Get outta my shop before I blow your head off, you long-haired faggy little gook!
Tao is terrified, frozen stiff.
Walt and the Barber throw their heads back and laugh.
The Barber lowers the shotgun.
WALT
Jesus Christ, Toad, you don't walk in and insult a guy. What are you, an idiot?
TAO
But... but that's what you said.
That's what you said men say.
WALT
Not if you never met the guy. If you say that shit to the wrong stranger, they'll blow your goddamned gook head off!
