Cover art for Arsenal lyrics by Kidneythieves

This song is about a girl who is mad at someone or a group of people or perhaps the world and she waits to exact her revenge. She sits there, cold and calculating, waiting for the opportune moment, and they don't believe her and that she will get back at them. Like: "quiet and protected slightly anorexic" I think she's spending time just plotting her revenge and perhaps forgets to eat. "(She Waits) she's a time bomb, with her vibe on she's gonna use it and surprise them she's a time bomb, with her vibe on they'll never know where she got her weapon." She waits to get revenge till the perfect time, she's waiting to explode and thing's are going her way. She's going to have her revenge one day and it will surprise them. They won't know where she got her weapon is like they won't know how she got back at them so bad. "they really don't believe her she keeps it all a secret found the Golden Muses doesn't need to prove it" PErhaps she's told them she will get back, but they don't believe that it will happen, that she's all talk. She's found inspiration and perhaps is getting what she needs to get back at them, and she doesn't need to flaunt it, she's just going to get them without warning. "naive little pieces she thought that they could see her but soon the Desert Pigs will know she's holding in an arsenal." She thought they understood that she was going to get revenge, but they really couldn't because they are too naive, but soon they will know she has sat quietly and gathered up all she needs to get back at them big time and she has an arsenal of ways to get back now and soon she will.

I don't know, I could be wrong, but it's my take on the song.
