倒霉

Almost forgot this one...

The day after we returned from Japan, we had a dinner with 奶奶 side of the family. Before the dinner, April for some reason pissed at Mommy. Mommy couldn't remember what it was. But she used this new word she learnt...

April:你倒霉呀你！

Mommy was very surprised. And explained to her that it's not an appropriate word to use, it's extremely impolite. She immediately kicked back...

April:你讨厌呀你！

Mommy gave her credit for using a more moderate word and was carrying a smile which made her angrier.
