The element of a party that would make it the best time ever. The reason people will come back to your party. The reason people talk about your party for years afterwards.

Also...The black guy at the party (usually a tailgate) that everyone is excited is coming. He's loud, obnoxious, HILARIOUS, and can drink for hours on end.
I thought this weekend was going to suck but I forgot about "The Vactor Factor"! It's goin to be awesome!

Tailgater 1: "I don't know if I can go to the game on Saturday."
Tailgater 2: "The Vactor Factor will be there."
Tailgater 1: "well then I'm DEFINITELY going to make it!"
