This expression is usually screamed, but does not necessarily have to be yelled at the specified target. Used when someone is engaging you in a story or conversation that you don't feel like hearing. When used correctly the speaker will feel embarassed, and immediately stop boring you with their story. Can be translated to "I don't care," or "Shut the hell up."
