俚语被认为是正式的语言吗（34cut）

Friends ( Season 7 ) Episode 18

在《老友记》第七季18集的剧情中，身为教授的Ross在下课后留下了一名期中考试挂科的同学，告诉他成绩只有7分（满分100），这位同学则因为特殊原因请求Ross放他一马，他是这么说的 "Well, maybe you can cut me some slack"，短语"cut someone some slack"的英文释义为"to not judge someone as severely as you usually would because they are having problems at the present time"，翻译过来就是“放过某人一马”，我们来看一些例句：

• "Andrew's late again." "Cut him some slack - his wife just had a baby." - “Andrew又迟到了。” “放他一马吧，他的妻子刚生了孩子。”
• "When you're new at a job, colleagues and bosses cut you some slack. They forgive minor mistakes because you're new." - “当你是新人的时候，同事和老板都不会对你严格要求，他们会允许你犯一些小错。”
• "It's your first day here, so I'm going to cut you some slack this time. Next time, you need to do much better." - “看在这是你的第一天，我就放你一马，下次你可得做得更好。”

短语"cut some slack"源自开帆船时松弛绳索的操作，毕竟有时候放松紧绷的绳索才能更顺利地乘风破浪。
