如果有人耍滑头或调皮捣蛋，我们就可以说他是cheeky monkey。

【例句】
My friend was trying to get free copies of her favourite newspaper by queuing up in different locations. She is such a cheeky monkey.
我朋友为了免费拿到她最喜欢的报刊，竟然跑去不同的地点排队领取，真是滑头。

You know John is not telling the truth about the price of his car. It cannot cost a million dollars. He is just being a cheeky monkey.
约翰对他那辆汽车的价格并没有说真话，肯定花不了一百万美元。他只是在耍滑头装阔气。
