I think many of you are or have been deal with Chinese, if you know some HOT slang, it can make each other feel better.
So, here we go:
神马都是浮云:Shen ma dou shi fuyun. (神马 means anything, 浮云 means nothing, so anything is nothing)
If you get a quote in a very high price, you can say: Price is FUYUN。
哥,伤不起:Ge, shang bu qi. (哥 means I(boy but not girl), I can't stand the hurts!)
姐,伤不起:Jie, shang bu qi. (姐 mans I(girl but not boy), I can't stand the hurts!)
if you need something, but you can't make sure the quality for the price, and it may make you a big lose, you can say: Oh, no, Ge, shang bu qi.
These can be used anywhere( except official place).
Hope you guys like it.
