Into naked fistfights.
Nude, primal brawls.
In showers, saunas, just a naked streetfight.
No, I'm not into extremely bloody fights and deaths... just in case.
If it's a well choreographed naked fight in a movie, more than welcome.
If it's a real fight, most fighters should be (in my mind) skilled fighters, black belts in martial arts.
Imagination can fly far away.
