Yes, maybe if you don’t like to use dirty words, it’s not very interesting. But I think it’s a great way to make yourself feel more Chinese. (I’m always searching for ways to feel more Chinese! Who isn’t, really?) Swear like the locals!

In fact, the Wikipedia on Mandarin Slang has plenty of terms that aren’t curses. And might be quite useful:

• gǔndàn (Simplified Chinese: 滚蛋; Traditional Chinese: 滾蛋) = get lost!
  –> this one literally means “roll egg,” so it’s means like “roll away like an egg”
• wōnang fèi (Simplified Chinese: 窝囊废; Traditional Chinese: 窩囊廢) = loser
