Meat Grinder 

Set-up: Everyone stands in a fairly large circle. The leader of the game numbers everyone off. 

Gameplay: 
The leader or reeve calls out two numbers, those two people go in and fight. THis continues for as long as you want. If the leader/reeve calls "Meatgrinder", everyone runs in and fights. The leader/reeve can also call out garb colors, weapon styles, or anything. Also, people that form the circle can poke fighters with their weapon if they get close enough (They must stand in their spot however).
