Especially useful in countries that call it soccer, (eg USA, Australia), where snobby soccer fans insist on calling it 'football' even though there is already a game called football in that country.
Matt: It's called FOOTBALL you jerk. The whole world calls it football.
Dave: But it's called soccer in this country, what is your problem with that? We already have a game called football here.
Matt: My problem is you're an ignorant piece of trash, and your so-called 'football' is the most pathetic game in the world.
Dave: Now I know why they call it Snob Ball. How do you expect to attract people to your sport with that sort of attitude?
You see, in each of these countries there is an undercurrent of soccer fans with a collective chip on their shoulder, who resent the fact that soccer is regarded locally as a boring and weak European game, enjoyed here only by "Children, Snobs and Hooligans". Many of these soccer fans secretly dream of a day when the local game of Football is wiped out and forgotten. Some of them even work in the media.
When Soccer converts to Snob Ball, it harnesses this resentment in the form of snobbery, firstly by sending out a strong signal that it is going to hijack the word "Football", a long-held ambition of many Soccer Snobs. Within a short space of time, the national soccer body changes its name, for instance from "Soccer Australia" to "Football Federation Australia". It forces all state/province and local-level soccer clubs and associations to do the same. It places slogans on television and on billboards nationwide linking Soccer with the word "Football". For greater effect, this may coincide with a high-profile revamp of the national soccer league.
Players and officials of the sport are instructed to insert the word "Football" as many times into one sentence as possible when speaking to the media (even shamelessly stealing the exact name of the existing sport, for example "Australian Football" to describe Australians playing soccer). And a previously invisible army of Soccer Snobs does the same, in schools, workplaces and on the internet.
Through some mixture of snobbery and commercial agreement, certain media organisations also scramble to change their policy on the word "Football". The end result of Snob Ball is that it becomes difficult for even the most passionate football fan to hear the word "football" without thinking about soccer.
Look out North America, Snob Ball could happen to you too some day.
