1.
Metro fail is derived from a company which runs the public train network in Melbourne. Due to the fact they are constantly late, delayed, trains canceled. And when they do come they are over packed.

So metro got the nick name fail. Then after that, the term 'Metro Fail' arose which has taken a similar meaning to 'Epic Fail' (or to fail really badly) The word is commonly used on instant messaging and social networking websites.
You mean it was a metro fail?
