To reply to one of the early post...
A bad boy ugly as shit and no personality. He has a mohawk and lip piercing just to look like all others. He claims to like metal bands just for the image as he would be slagging them off at home and admits to himself that he has never heard of legends like Iron Maiden. He is in reality a sheep as there are plenty of boys like him as they think they can stand out in a crowd when each of them are just like him. He likes to think every girls thinks he does is hot and he thinks in his brain he really is. He likes to think he stands out by smoking just to rebel against his pampered life
Guys, everytime you see one, just do everybody a favour, smack him one in the face even if its unprovoked and there is no reason for it.
