去 spice something up 的意思就是放更多香料在食物或饮料里使其更有滋味。你也可以 spice up 一段讲话、一个表演或活动：在这里就不是放调料了，而是在其中加入引人趣味的内容。
- This salad was a bit boring so I spiced it up with some chilli sauce.
- Martin's speech was really dull. He should have spiced it up with some jokes!
值得注意的是，如果某人被形容为as salt and pepper，就是说他原来深色的头发已经开始掺杂白发了。
- Mark used to have lovely black hair but now he's salt and pepper. But you know what, I like it!
