Hi, got to be fast because I have only three minutes left on this coin. Look up, or you might already know about polari, gay/Jewish slang. Example: NAFF - not available for fucking, supposedly what gays called straights at times. Kenneth Williams and Hugh Paddick built an act in Round The Horne etc on polari. Also a lot of non-gay slang comes from Manchester merchants. It became very trendy in the Sixties to become pseudo working class and use a lot of that slang.
