As we all know, there are trends from our younger years that ruled past decades but aren't popular anymore (ahem, skinny jeans)...
...and there are things we thought were funny back then that would be every kind of inappropriate today...
...and there are endless styles that ended up being more dated than timeless, from fashion to hair to makeup.
And before you know it, the things you love are not exactly the picks du jour.
That's why I want to know from all those older and wiser: What are the things that tweens, teens, and young adults are currently obsessed with that they'll probably think twice about once they get older?
