I would have to say C... b/c the only time you'd see it is on an ad!  I think that is the ugliest look ever... and these punks are always puling their pants up b/c they keep falling.  I don't think it's GROSS which is why I can't pick B.  I just think it's DUMB.  God help me if I have a boy that tries to do that!  He won't get away with it as long as I can see him :)
