Good post Tez, and to answer your question, no it does not. In USA Catch as Catch Can has a long history and means to get a hold any way you can. Depending on where you are it went by various names like, No Holds Barred or Rough & Tumble. I think people mistake it for WWF style a lot because it branched off into that from the circus back in 1940s.
Catch even less well know in US than UK, and that sayin something!!
Only haters love in in US for sure.
