The ear or lip discs always get me.
I was at a bar recently where a really cute bartender clearly had a disc in her ear that she had take out, maybe just for work, maybe for good. It looks horrific to see this giant earlobe hole just haning there. I was complaining about it outside afterwards when the guy at the door I'm talking to said that was his GF. He didn't get mad luckily, he agreed with me. I haven't met anyone who just stops at a very small one either; they just keep increasing the size.
I feel like in 20 years we are going to have a tons of freaky middle age people. Old piercing and disc holes hanging out and wrinkled, faded tattoo sleeves everywhere.
