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.

silflay 

From Richard Adam's book Watership Down - it's a word that's part of the rabbit language Lapine - it means to go above ground to eat.

I didn't silflay with the rest of the warren this morning - I'll go tonight.

Sifl and Olly

A sock puppet show for stoners, where Sifl and Olly host their own show in their apartment. They would do skits such as "Calls from the Public" and "Rock Facts." Their friend Chester comes on and sings every once in a while.

Dude, I was so stoned last night that I watched Sifl and Olly!
