6661 

Zacky Vengeance uses the number 6661 in his online clothing line: Vengeance University. The number is also 1999 upside down, which is the year that Avenged Sevenfold (of which Zacky Vengeance is a founding member of) was established. But the significance is that 6661 means that the devil (the 666 part) won (1). Zacky Vengeance commonly displays this number on his guitar.

Someone else: What is 6661?
Me: The Devil Won.

Someonce else: Where does it come from?
Me: Zacky Vengeance of Avenged Sevenfold.
