Get up on the wrong side of bed (or get out of the wrong side of bed, or wake up on the wrong side of bed): To seem grouchy on a particular day; to begin the day feeling unhappy and uncomfortable.
这个常用口语的字面意思是“睡觉睡错边了”或者“起床起错边了”。每个人睡觉的时候都会习惯睡床的某一边,如果睡错边了,醒来的时候会感到很不舒服,心情不好。所以当一个人某天心情不好,脾气烦躁,或感到干什么都不顺利的时候,就可以用睡觉睡错边了来形容。
造句:
1). Did you get up on the wrong side of bed this morning? You are a real grouch! (你今天早上是不是发现你睡觉睡错边了?你是满腹牢骚。)
2). I got up on the wrong side of bed yesterday, and everything that could go wrong did! (我昨天可以说是万事不顺,所有可能出错的事都发生了。)
