I used to do this when I was younger. I'd just go out to a bar by myself and somehow become attached to a random friend group that I'd never met before.
For reasons I don't understand, people will just come up and talk to me whenever I'm out in public. Usually it's whatever odd man out of a group is. So I often wind up being dragged over by the lone single person in a group of couples. I'm apparently approachable looking, idk
I don't believe in belts. There should be no ranking system for toughness.
