You'll probably want to restrain yourself somehow. The brand will wobble and you might start jittering the forget out from the pain and it'll look like stuff. If you want to go for this kind of br00tal edgemaster stuff you might as well just go with scarification, it'll probably look the same but more precise. It's going to hurt a lot more than a cigarette burn most likely.
Use a good brand with good metal. Also this is a bad idea, but who am I to stop someone from attaining their dreams?
EDIT: Read through the thread. This is going to hurt SO much more than a needle. It's going to be pretty extreme deliberating pain throughout and after. Tattoos are lesser pain over a longer period of time. Have a good bit of ice cold water on standby.
