Supermoon 

A phenomena that occurs only one every so often, when the moon reaches the point where it is as close to the earth as it can be. It is the biggest and brightest and most mayhemic moon you can see, and has been known to induce feral behavior in animals, people, and werewolves. Other side effects include howling, excessive sexual urges, a need to be outside, and most of all, a craving for Dinosuar BBQ.

Dude 1: Hey do you know about the supermoon?

Dude 2: Ya man, and I can't stop thinking about pulled pork!

Dude 1 Let's go outside and howl!

Dude 2: Ummmm no.
