My suggestion: Simplificatio Adstupefaciendi - A simplification with the purpose to astonish.

On top of sounding cool it is already astonishing to remember and to be able to spell it!

Basically you are expected to either just go in sick or take the day and not be paid. Also if you take the day, depending on how bad your boss is they could try to call you a no call/no show. A strike at best or a reason for termination at worst.
