A phrase used to tell another person to politely say, "I have no interest in continuing this conversation or listening to you complain." In its hardly ever used long form, it would be used as, "I don't know what to tell you to get you to shut up." Extensively used when people present you with a problem, you offer advice to them on viable solutions, but they come up with excuses why they can't follow your advice.
Person A; "complain, complain, complain. My car broke and I can't get to work now. And boss says he'll fire me if I miss another day!"
Person B; "Take the bus."
Person A; "There's no bus route within a quarter mile, and my feet hurt so much."
Person B; "Take a cab."

But you didn't have to cut me off
Make out like it never happened and that we were nothing
And I don't even need your love
But you treat me like a stranger and that feels so rough
No, you didn't have to stoop so low
Have your friends collect your records
And then change your number
I guess that I don't need that though
Now you're just somebody that I used to know
Now you're just somebody that I used to know
Now you're just somebody that I used to know
