There has been some great topiccs about fresh ideas for matches that are a bit out of the ordinary, so I thought I would suggest something I did recently which worked well.
It was an asset destruction match, which I tried with a friend on here.
What happens is each girl picks one part of her body, and it can be any part, from face, to chest, to legs, to tummy, to crotch, it can be anything to suit the styles and the limits. Then the match is started. The aim is to 'destroy' that particular body part. Again this comes down to limits, those people into very rough matches will go a lot further than those with lighter limits, where it could be a case of a submission or ko has to be gained by something to that area.
The difference is, its a normal style match, so say if I had to go for my opponents chest, I wouldnt spend all match doign that, I'd much rather lock her in a pin, trap her arms and then go for it. If it were her legs then I would have to use other holds and moves to work my opponent into a position where I could work her legs effectively. It gives the trash talk in the match a bit of a focal point, and it gives you a good rivalry. Of course other stakes can be thrown in depending on the opponent but its a theme which would work for most styles.
I will come back with some other ideas, but I did like this thread idea, so thought I would add an idea!
