You ever watch a male lion at the head of it's pride?
Confident, bold, aggressive, tough, and every other thing that has to do with pigheaded manliness!

So when you feel like a mix between a fucking MAN and an Animal then you are feeling it.
Roid Rage..... If you are an asshole before then you will just be a bigger asshole while on. Roid Rage is a myth. I've been Roid Raging since I was like 12 before I ever knew what juice was.
