If you had a groupchat of sorts of people in the general area and whenever you felt like receiving a wedgie you could post that you would be bent over in a certain location at a certain time. Then someone could come, wedgie you and then move on.
Random idea, but it would be good for people who really enjoy the humiliation of public wedgies
So, for example, I'm from the North in the UK. So I could message that I would be tying my shoelaces outside of Old Trafford at 1pm and my blue animal print underwear would be sticking out of my jeans. Then someone near there could give me the wedgie I deserve
