What does this quote mean from The Exorcist?

Haha i knew this was going to be the quote you were talking about. I think it's just the demon goading Regan's mother, the 'C-word' is considered pretty offensive, I imagine more so back then. But like others said i think he/it was alluding to the 'crucifix scene'.

The Exorcist III is a 1990 American supernatural thriller and the 2d sequel of The Exorcist series, written and directed by way of William Peter Blatty. It's a movie adaptation of Blatty's novel, Legion (1983) and stars George C. Scott, Brad Dourif, Ed Flanders, and Nicol Williamson.

Wow, it's been a while, but I think you're wrong. The "a" in "canting" was a "u".

If you remember, the demon made her masturbate with the crucifix...

Cúnting, is a kind of English slur. Reagan, not Regan, accused the butler of being a former Nazi in hiding, and she urinated on the floor, etc.

"C*nting daughter"- Swear words were once more offensive than the widespread child sex-abuse and cover-up that occurred within the catholic church. And all other religions too, of course.

She was enjoying herself with a crucifix

The word is not "canting". Replace the "a" with "u".

.

then she says " Your mother cooks socks in hell"
