Why do kids walk around with their pants falling down?

Why do young guys wear their pants hanging down below their butts? It looks ridiculous and it’s impractical. What if you have to run away from a pit bull on the loose, or you get in a fight? Your pants will restrict your movement. An attacker could just yank them down around your ankles, and then he could easily knock you over and jump on your head.

And, yes, I’m asking a question, not just ranting. Every generation seems to follow fashions that the previous generation disapproves of. But this is just lemming-off-the-cliff stupid.
