AVENGED SEVENFOLD FANS! I NEED HELP!?

Try to keep cool, remember that they see girl fans all of the time and from what I have seen they're lovely guys, so compliment their music, maybe talk about it and have a nice chat, but try not to freak out, they'd be used to it but try not to make them feel uncomfortable. You're really lucky so if it is true then I hope you have a lot of fun!
