What is 变卦 (biàn guà)?

Have you ever stood up by someone, and that made you angry? Do you know how to describe such a behavior in Chinese? 

"变卦 (biàn guà)" means someone suddenly changes his/her mind on something that has already been decided. People usually use this word to express dissatisfaction to the person who has changed.

“变卦”是指某人已经决定好做某事又突然改变了主意。 说话人用这个词时，表示对突然改变的人或事不满或埋怨。

Examples:

1. Búshì yǐjīng shuōhǎo le míngtiān yìqǐ chūqù wánr, nǐ zěnme línshí biànguà le?

不是已经说好了明天一起出去玩儿，你怎么临时变卦了？

Haven't we decided to go out tomorrow? Why do you change your mind suddenly?
