What a difference a word makes. It's been a long time since I've seen this, so I didn't remember the scene.

I read the text first, where she says, "You're wearing your cocksucker suit" and thought this was one of the best lines ever.

But in the scene, it's "Your wearing your cocksucker."

It's so much better the first way, as it conjures an image of a special suit someone might wear for said occasion, OR a suit that only a jackass (AKA cocksucker) might wear. As it actually plays in the film, it's still funny, but in a more run-of-the-mill, silly way - a malaprop. The other images aren't conjured.

It really cracked me up when I read that.
