I'm confused here... I though that Ro-sham-bo was when both parties kicked each other as hard as possible in the groin until someone gave up or fell over. Like in South Park where Robert Smith "from the Cure!" Ro-sham-bos Cartman for the wristwatch radio.
And I leave you with the blurb from the Robert Rankin book "The Garden of Unearthly Delights" - Few people noticed it at first. The changes. The were subtle to begin with. Like when the Leader of the Opposition challenged the PM (Prime Minister) to step outside and settle things man to man. And the PM agreed.
