When someone hits on you who is not good looking or really old. In the case that this happens, you must yell "Nut Sack Delight" at the top of your lungs!!!
For example:

Guy is at tailor shop getting fitted for suit. An elderly woman comes out and measures him. At the end of all that... the guy is about to walk away when the woman says "Oh nice body" while staring at the guy's butt. Only problem? The woman is old enough to be the guy's grandma. = Nut Sack Delight.
