Yeah I remember this Vinnie Jones dialogue. And just what: it’s on imdb:

Bullet Tooth Tony: So, you are obviously the big dick. The men on the side of ya are your balls. There are two types of balls. There are big brave balls, and there are little mincey faggot balls.
Vinny: These are your last words, so make them a prayer.
Bullet Tooth Tony: Now, dicks have drive and clarity of vision, but they are not clever. They smell pussy and they want a piece of the action. And you thought you smelled some good old pussy, and have brought your two small mincey faggot balls along for a good old time. But you’ve got your parties mangled up. There’s no pussy here, just a dose that’ll make you wish you were born a woman. Like a prick, you are having second thoughts. You are shrinking, and your two little balls are shrinking with you. And the fact that you’ve got “Replica” written down the side of your gun…

[Zoom in on the side of Sol's gun, which indeed has "REPLICA" etched on the side; zoom out, as they sneak peeks at the sides of their guns]

Bullet Tooth Tony: And the fact that I’ve got “Desert Eagle point five O”…

[Withdraws his gun and puts it on the table]

Bullet Tooth Tony: Written down the side of mine…

[They look, zoom in on the side of his gun, which indeed has "DESERT EAGLE .50" etched on the side]

Bullet Tooth Tony: Should precipitate your balls into shrinking, along with your presence. Now… Fuck off!

This movie is definitely one of my grand favorites. We watched it a few years back and really loved the dialogue and the performance of Brad Pitt (a really surprising role, not the usual ‘beau’ and his accent is absolutely awfully special) and Vinnie Jones and the rest as well.

We specially liked the scene in the pub when Jones reacts to the buffoons’ threats with his ‘Desert Eagle .50′ and his wonderdul speech about ’shrinking balls’. We used to watch it over and over again to catch all the subtleties of the dialogue…
