I hope for god's sake you are kidding. If not you are a complete fucktard.
I put a tanto inside my gi-pants, walk up to a grappler, and ask about a roll on the mat. When he enters my guard, I press the tanto in my pants against his thighs, lean over and whisper in his ear "I love you". While he looks at me all confused I just reach down in my gi pants, get the tanto, and slice his throat, then get the eff out of there.
Then you can just log on to Kutaki and register your kill, for karma points.
