wake up/get up on the wrong side of the bed/get out of bed on the wrong side
有起床气/起床的方式不对/一大早起来心情不好
使用场景：
A：Why are you getting mad at me? Did I do anything wrong?
A：你干嘛冲我发火啊?我做错了啥?
B：Sorry, I got up on the wrong side of the bed.
B：不好意思哈，我这是起床气/一定是因为我起床的方式不对。
A：(shouting in a rage)
A：(怒吼中)
Others：(whispering)Sounds like someone got up on the wrong side of the bed this morning.
其他人：(窃窃私语)这人好大的起床气/某人是今天早上起床的方式不对吧……
所以，一大早心情不佳的、发脾气的，通通可以称之为getting up on the wrong side of the bed，总之都要怪wrong side of the bed。虽然对应的中文是“起床气”，但是小编觉得，说是“起床的方式不对”，似乎更可爱一点呢~
