This only applies when a groupie receives a facial from three, 6 stringed musician. Preferably of the metal genre, and not necessarily all at the same time. As groupies tend to go through members, keep track of who's face you blew your load on, and compare with the other band mates. If a groupie appears on 3 of the lists, she's been marked by three six stringed instruments..... 6-6-6 ...... thus, the mark of the beast.

The "two-backed beast" is a euphamism for having sex. For some reason, people can't just say "having sex," they have to come up with a clever way to say it.

the guitar that the kids who listen to slipknot, korn, and mudvayne will ask their parents to buy. Its made out of crap woods, low qualitypickups, and if you want it, a sub-standard trem. It would be a good starter guitar, if it wasn't about $400 for a cheap one.
