Terrific Lady Day 

A special day that a man gives to his significant other (girlfriend, fiance, wife) in which he does whatever she wants, whenever she wants. Most of the time, this is done to fix a screw-up, or obtain good graces in preparation for a future screw-up. As seen on the FX series "The League"

My wife is still mad at me for going to Vegas with the boys. Looks like I'm gonna have to give her a terrific lady day tomorrow to make things right.
