IMO swearing is useless and immature. There are plenty more vivid words you can describe things with than constantly swearing to try and sound "cool" or "mature". It is also a great way to lose an argument. It shows the other person that they are flustering you and basically overpowering the conversation.
Take Furdle and me for example, he is always bashing my selfies and stuff. I have no idea why he even started. Every time he saw a spark of an opportunity to create an argument he would pour gasoline over it metaphorically speaking. From what I have seen so far he has always been like that. A drama of his completely backfired on him because of a comment he made to me. He would send me PM's filled with cursing, maybe trying to intimidate me, but it just showed me he didn't know how to handle the situation. His former account got banned for flaming me in PRLPoY. I don't know what his problem is but he is eager for fights bit never truly finishes them. He hasn't phased me one bit, maybe even boosted my confidence here. Swearing gets you nowhere. Speak with respect. It will carry you places.
