What Are The Two Words 是哪两个词

A very nice old lady had a few words to say to her granddaughter. My dear, said the old lady, I wish you would do something for me. I wish you would promise me never to use two words. One is ‘lousy’ and the other is ‘swell’. Would you promise me that?

Why, sure, Granny, said the girl. What are the two words?

一个非常高贵的老夫人有几句话要对她的孙女说。我亲爱的，老夫人说：我希望你能帮我一个忙。我要你答应永远不要用两个词，一个是“讨厌的”，另一个是“极好的”。你能答应我吗？

噢，当然，奶奶，女孩说：是哪两个词？
