I admit it, I was once guilty of the overalls with one side down thing and the boxers as shorts craze... but I was in elementary school and MY MOM MADE ME DO IT. I swear.
The popped collars thing looks really stupid. The girls pants on guys... not cool either. Some friend of a friend of mine came in to my work the other day to apply for a job and he was wearing girls' low rise pants... and you could see his pubes!!! Eewwwww
