"This marker is cool and will bruise your buddies up."
I hate this mentality with people. I know it's fun after the day to check out welts and see everybody's battle wounds but so many people think only about bruising or causing that little pain. These people tend to be the ones who progress to cranking velocity and hurting someone.
Sorry, I don't mean the seller is that kind of person I just saw it and had to say something because of recent experience with some unsavory individuals. Every now and then I have to put in a misplaced rant.
