I finally got used to seeing them sometime in high school, but I still think that gauges look fucking disgusting. You're stretching your earlobe out to lengths that it was never meant to be stretched to and then sticking a piece of metal in there? WHY!?
And I even listened to metalcore in high school!
By the way, if they have gauges then it's almost certain that they listen to something like this. Or this, if their tastes are terrible. Or at least that's how it was when I was in high school, they might all listen to Justin Beiber now.
