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.
