The first use of the word "hamburgerisation" can be traced to Sir Arthur "Bomber" Harris, referring to the bombing of Dresden, Germany, in February, 1945. The city was reduced to rubble, as though it had been through a meat grinder.
Recently, the word has been re-coined by left-wing activist groups, but with no specific meaning. Depending on who is using the word, and in what context, it may mean "commercialization", "globalization", "cultural homogenization", "conversion of forest to grazing land" or even "corporate hotel development". For anti-capitalists, the word doesn't have to be meaningful; it just has to imply an analogy to a global fast-food franchise to evoke an emotional response.
Perhaps this is "hamburgerisation" of English vocabulary.
