I asked some neighborhood kids about this whole pants hanging low thingy and they told me that it's a prison statement. As in, our heroes are prisoners and this is how we support them by showing solidarity or some nonsense. They could have been messing with me but mostly thugs started this wonderful fashion statement.
I can't see how they figure they can break the law and run fast with all that solidarity hanging below their butts and not get caught lol
That's funny because all I heard are prisoners saying that wearing your pants like that is asking to get raped in prison. I'd guess some kids my think that but that's not the meaning for all.
