What I want to address in this article are the right and wrong ways to swear. Swearing can make a story ten times more amusing. It can make a joke so much easier to laugh at. I can't even count the number of times that a friend was recounting a funny story to me and when that unexpected curse word made its entrance, I could not help but laugh. I do not mean to say that profanity is a necessity for making someone laugh, but used sparingly and in the proper context, it can be perfectly hilarious.
Colorful language can also aid in getting a point across.
This relates to the previous paragraph. In speaking about how you feel about something, cursing may help whoever you are speaking to to realize just how serious you are about your point. Again, I am not saying that swearing is necessary for getting a point across, but it can help if you feel the need. I really love language. In fact, that's what I'm studying here.
