Same concept as Standard Ro Sham Bo, only with anti-fraud laws/rules set in place.
1.) Both opponents must wear speedos, neither opponent is allowed to perform the actual kicks.
2.) A referee is called out who then in turn nominates kickers or one kicker. Those Kicker/Kickers must be of equal bias towards the opponents.
3.) No shoes allowed on kickers
4.) No girlie kicks
5.) What happens in Ro Sham Bo, stays in Ro Sham Bo
"Alex and I were persuaded into Ro Sham Bo last night. The spoils were $50.00."
"Did you play?"
"Yeah but I called out for Professional Ro Sham Bo. In any case I lost! I did take 27 kicks before I finally went down though."

New and improved Ro Sham Bo. It is a professional game designed to where the games can not be "set up" or involve cheating or degrees of unfairness.
The main reason pertains to the degree of unfairness. In Standard RSB two males kick each other in the nuts until there is only one left standing and he is the winner.
However, if one man has stronger legs than the other man, the man with stronger legs is given the advantage. Up to date this method is largely becoming illegalized and has been upgraded for the new and improved "Professional Ro Sham Bo".
(Although "Standard RSB may still sometimes be played for fun.)
In Professional RSB there is normally money or spoils at stake. Therefore Professional RSB is often mandated. Also any opponent may at anytime call out for Professional RSB and if so, must be enacted.
Rule #1) In Professional RSB also known (as Third Party Ro Sham Bo), one or more unbiased kickers must be nominated. If a biased kicker is nominated towards one of the opponents than yet another kicker must be added of equal bias to the other opponent.
The kicker must kick each opponent than step back and let the other kicker proceed for their round. And on and on in this fashion.
Rule#2) BOTH opponents must wear speedos. This is to ensure to the video taped audience/judges/spectators that there is no wearing of "cups".
Rule#3) An unbiased referee must be present to nominate kicker/kickers who must be of equal bias towards both opponents. The ref will call out the nature of the spoils, (normally money from the spectators but not always)
Rule#4) GIRLIE KICKS ARE STRICTLY PROHIBITED!
"Hey John, I'll Ro Sham Bo you for 50 bucks. There's ten people in the room and Dean said they'd all throw in $5 to watch. Dean called out that he's Ref."
"Fuck you! I'll play you but Dean's not going to be Ref, anyone but him, I don't trust you two. And we're playing Professional Ro Sham Bo or I'm out."
"Your on! Jenny's Ref then."
"Fine, Jenny, who are you nominating as Kicker?"
"I am nominating BOTH Lisa and Carrie as kickers."

Get the Professional Ro Sham Bo mug.
The traditional yet out dated form of unregulated Ro Sham Bo, also known as Standard Ro Sham Bo. It is a contest in which two guys kick each other in the nuts until there is only one left standing.
Standard RSB has been replaced by "Professional RSB"
Did you hear about John and Steve? They both liked this chic at a party and the chic found out. She laughed and told them both to Ro Sham Bo for a hand job from her as the spoils.
They agreed, everyone in the house had to throw down a couple of bucks to watch, which went to the chic as she was using herself as the prize.
They played Standard Ro Sham Bo because the chic demanded that standard be the game they play and neither one of them protested.
In the end Steve went down. But he did very well from having been kicked 42 times in the sack!
Afterwards, the chic took John in the room and wanked him! I don't know if the hand job was worth it!

Newest form a Ro Sham Bo created for the fairness of contest. This form uses a third person to play "kicker". The kicker is used to equalize the strength of the kicks, enabling a sense of fairness to degrees of pain endured.
The Kickers kicks are equal in caliber of force as opposed to standard RSB which puts the man with stronger legs in favor, as well as leaves kicking force unregulated.
The third party kicker must be unbiased towards the two opponents or hate them both equally.
Third party Ro Sham Bo is often initiated when playing for money or other spoils in which the match must be fair.
Saturday night was insane! We all got drunk and later on Tim and Pete had some kind of dispute.The crowd then called out for RO SHAM BO! The two opponents agreed, but only if it was "Third Party Ro Sham Bo", and everyone threw down $5 to watch.
John, acting as Ref, nominated Christina to be Kicker. Christina kicked both opponents with equal strength repeatedly in the crotch, for what seemed like hours...Eventually Tim whimpered in defeat, and Pete received the winnings. The winnings was a hand job from Christina, who of course, received all of the spectator cash.
