Do yourself a favor, and don't.
Horseplay is one thing, but getting into an actual fight if you can avoid it is just dumb. Sure, you might get a rush, but if one of you doesn't know what you're doing, someone can get really hurt.
I was on the wrestling team at my high school, which means there was a degree of safety and supervision you won't have in a real fight. And I still cracked two bones, tore ligaments in my knee, and personally witnessed 2 separate dislocations, all during my first (and only) season. I also went up against a guy about 4 inches taller than me who I literally outmassed 2:1, and who bent me in pretzel within 5 seconds.
If you have to fight, don't do anything fancy. And if you're going for submission, be careful with your holds. You want to be VERY careful with your holds.
I believe in honesty, civility, generosity, practicality, and impartiality.
