I think it's a disgusting trend...it just looks tacky on various levels. I don't care how old the person is...15 or 25...gross! And then there is a sort of "walk" that goes along with it. It looks like the dude took a sh*t in his pants and he doesn't want itto touch his bum,because then that would be an even larger mess. Yup,thats what it looks like to me.Instant turn off. :/
I can tolerate it if the guy was still in high school but when you're past the age of 20 maybe, it just looks really sloppy on your part and if anything, it will probably make people judge you about your personality even though all you're doing is sagging your pants a bit.
