Aikido is love you know. So...
When your taken down by a BJJ'er, grab his arse and give him a big juicy kiss. Guaranteed to end the fight in an instance and he will probably never attack you again.
Ps. do not try this technique if your currently serving time.
waitaminnut. You're going to take guys that spend hours and hours a week rolling around with other guys between their legs, mounted on top, and back mounted (and lets not forget north/south) - and try and out gay them into submission?? Good luck with that.
Anyone got a link to the bjj is the gayest sport ever vid?
