Nope.  The word "hippie" was in use before it referred to the hippie subculture.  Read Hippie (etymology).  Unless you can find a secondary source showing that the Rolling Stones were using it to refer to the subculture, then you don't have a dispute.  We don't do original research.  The Fallon citation isn't sourced to Fallon: it's found in multiple sources that make that claim.  Take a look at the citation in the Hippie article: Perry 2005, p. 19; Sinclair, Mick. (2004) San Francisco: A Cultural and Literary History. Signal Books. p. 205. ISBN 1902669649; Singleton, Carl. Wildin, Rowena. (1999). The Sixties in America. Salem Press. p. 334. ISBN 0893569828; Stevens 1998, pp. 299-300; Tompkins 2001, vol. 7: 1960-1969.  Now, all you have to do is find one that refers to the Rolling Stones.  The addition of McCleary's "numerous theories abound as to the origin of this word" is a great start in the right direction.  The next step is to find sources for additional theories.  I recommend using the library.  Good luck. — | Talk
