Bad Behavior on Trains

I'm at my Mom's house, to take her for her annual Mother's Day theatre outing (which is this afternoon, not tomorrow, for reasons of convenience). Amtrak was okay since I got a seat in the quiet car and the conductor was vigilant about tossing out the person who didn't grasp the concept of not using a cell phone there. But I was a bit amazed by some teenagers on the LIRR.

On what planet is it socially acceptable to wash out your new belly button piercing with saline on a commuter train?
