We had things like this a lot when I was in school. Bunch of us would meet up and challenge each other.
At my school to reduce fights in the halls. Anyone could give any coach a letter calling out another student. It had to be hand written describing why you had a problem with the person. The coach would present the letter to the other student if they accepted then you meet with the coach before school in the field house or gym. Put on the gloves and go at it as long as you could stand it.
It settled a lot of problems before they got out of hand. When I was in school kids carried deer rifles to school to. What happen to the good old days.
