查了一圈字典，是不是英式和美式意思不一样？
美式表示生气，英式表示迷恋？
剑桥词典里面只有一个迷恋的意思
be mad about someone/something
to love someone or something:
He's the first real boyfriend she's had and she's mad about him.
他是她第一个真正的男朋友，她很迷恋他。

韦氏词典：
informal : intensely angry or displeased
What are you so mad about?
Everyone was mad about the delay.
That kind of behavior really gets me mad.
I'm so mad I could spit.
