Going to see a man about a horse

Something you say when you are leaving in order to conceal your true purpose for leaving especially if you are going to see your drug dealer or going to get high.

Me: Where you going, Brian?
Brian: I'm going to see a man about a horse.
Joe: Hide the snacks...He's gonna have the munchies when he gets back!
Me: Yeah...You wanna go to the bar?
Joe: Yeah
