Holy mackerel, do you really think all the things you thought were cool back then were? I imagine most people of the generation above thought "what a knob" to most of the things we thought were cool. You're a bit young to be forgetting what being a teenager is like, but duckface is bang on trend at the moment and in fashion. Sure, it looks ridiculous to a lot of people, but that's what's in. Deal with it, it's hurting nobody.
