我们大都知道lame表示“跛腿的”，当然lame用在俚语里就不是这个意思了，它的意思跟sweet正好相反，表示“糟糕的，差劲的”。
例如：
That joke Karen told me was so lame. I couldn't believe it. She tried to be funny, but the punch line didn't make anybody laugh. I think her sense of humor is really weird.
Karen讲给我听的那个笑话真糟糕，简直令人难以置信。她拼命想说得滑稽，但是她那句逗笑的话却一点没引人发笑。我觉得她的幽默感有问题。
Lame可以用来描绘各种不同性质的糟糕或者令人生厌的情况。
例如：The Introduction to Economics class is so lame! The professor puts us all to sleep with his boring lectures. He doesn't teach anything practical or interesting. I want to switch classes.
经济学导论可真差劲！那位教授枯燥的讲课听得叫人都睡着了。他教的东西一点都没实用意义。我可要换班了。
