Answer 3

It is sort of an insulting way to tell people to go away, or mind their own business, or to stop doing or saying something that bothers the person.  

The origin of the meaning is basically, "stop worrying about me and get your own life."

Answer 4

It means that the person addressed has been wasting himself on trivia and throwing his life away. The " get" is an Americanism.
