That picture is right on. That is indeed how they look.

The answer: Because they want to emulate what they see on TV, specifically rap and hip-hop videos. It's no longer specific to race, it has now become specific to those that are just plain and simple, a damn fool. They can't even walk normal. I saw one guy trying to jog down the street looking like that (presumably chasing after a "shorty" or running from the law; it's safe to assume he wasn't in a hurry to make it on time to a job that you and I would hold in high regard); it was quite comical. I see it day in and out here and every time I do I wish, sometimes out loud, that they fall flat on their face. Ha! Yeah it annoys the heck out of me.
