Sinfluenza 

The debilitating condition suffered for approximately 1 to 3 business days after a wild weekend in Las Vegas, New York City, or another recognized center of partying and nightlife.

I called in sick to work because I spent the weekend in Vegas and I came down with a case of Sinfluenza.
