Crazy Hairstyles

Why do people have crazy hairstyles?I wonder why...I have a crazy hairstyle too..But not too over like those peoples..Some have spiky hair..Like mine but not to spiky like those..For boys,i suggest them to botak their heads..cuz if you keep long hair,people will say you have a brain disorder,a wannabe rocker or a girl..that is gay...For girls,they should not have long hairs like Juliet cuz if you sit and the next person sit beside you,your hair could have been seated by a person or tons of person...Some people say crazy hairstyles are weird hairstyles..But for what i know long hairs are scary!Haha!Should i cut my hair or not?Ok that is so out of the subject..
