A fanfiction pairing involving both Zacky Vengeance (Avenged Sevenfold) and Frank Iero (My Chemical Romance). The fanfiction is very obviously band slash, as the both of them are guys and in bands. Most of the reason that they are paired together is because they resemble one another, Frank usually being the bottom while Zacky takes place on top.
Also known as Fracky, or Zankie.
Man, I really love the Frengeance pairing!
