Get a Life

[Antonio]

I have several definitions for this phrase in English, here we go:

1.-To have fun.
2.-To do something different (E.G. Change your lifestyle)
3.-Often used as an instruction to someone who complains.
4.-Become aware or learn how.
5.-Get a well-balanced life (become happy, successful, etc.)
6.-Stop bothering me.

Now my main question is this, which of these meanings, apply more for the phrase "Get a life" and can you give an example of each one, if were the case, to understand better the phrase and the situation too.

Mainly, number six applies here, altho one could also say that number three fits. Keep in mind that the phrase is intended sarcastically.
