I believe that scripture is pretty clear on this matter. Especially if we look into the book of James. It speaks of our tongues as a double edged sword. For from it comes praise to God, then yet....some of the most insulting words towards one another. So when the question is asked in terms of curse words, I would think that such a passage is not limited to them alone but rather just about any slanderous or illy intended remark.
James 3:5-12 (King James Version) 5Even so the tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth! 6And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell. 7For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind: 8But the tongue can no man tame; it is an unruly evil, full of deadly poison. 9Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God. 10Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be. 11Doth a fountain send forth at the same place sweet water and bitter? 12Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
I apologize should any offense be taken. None was meant.
May God Bless You
