Underlay for the overplay

This is when someone spins you that you made plans with to go be with someone else. A great lie told to keep oneself out of the dog house or look good in front of a certain group of people. Giving an elaborate excuse that's usually not true for why you can't , didn't , or won't be able to do something.

Saturday I had two girls coming over at the same time so I had to think quick and told one that my cousin was in the hospital but that was just the "underlay for the overplay" so I didn't get busted.
