A Vulgar Guy I had a chip on my shoulder today. I've joined in an English tribe where a group of people have common interest in learning English language. There are dozens of chatting rooms for people to speak english. Today when I had nice conversation with a partner in a chatting room. All of a sudden, a vulgar guy interjected our conversation rudely. And he said neither of you can speak English fluently. And he continued insulting and belittling us by words and texts. He is really pissed us off. My partner grined and bear it. But I fought back by saying he is a twat,bimbo,sodding frog. But he was still attacking us by words. What other bad words I can use to fight back that unscrupulous guy?
