Used to emphasize that someone else has done or said something stupid or silly. Primarily heard in UK. Hark at him, telling me what to do when his own life is a mess. A: "Hey, Paul, listen to this! I've got a great idea to get rich!" B: "Hark at you, back again with another ridiculous scheme!" Hark at you, talking back to your mother like that. Enjoy your scolding!
