"Cursing," what we call slang is not sinful. End of story.

It may not be perfectly appropriate (read: modest) at all times. But it's not sinful.

One of the most beautiful stories of conversion come at the climax of the story, where the drug addict who was running away from the Hound of Heaven, finally says "F$#$#* it, I quit," indicating her emotional surrender to God. The way it was said was actually quite beautiful. May not float all of our boats, but just throwing that out there.
