Listen to "Otherworld" (the metal tune at the beginning of FFX) before you go to practice/ex-friend mutilating session.

"FIGHT!!! FIGHT!!! FIGHT!!! FIGHT!!! FIIIIIIIGHT!!!"

And remember to tape it!!!! Get your other buddies to take your or their cameras.

This reminds me of the friends episode where Ross was trying to impress his British girlfriend Emily by playing rugby with her friends, and he had to get all diiiiiirty to defend himself in game.
