Oh I am quite aware of what elitist means.
The belief that certain persons or members of certain classes or groups deserve favored treatment by virtue of their perceived superiority, as in intellect, social status, or financial resources. - Dictionary.com
AKA: We are true soccer fans, as someone that does not watch soccer on TV constantly throughout the year, you guys don't deserve to watch the World Cup
The "group" is true soccer fans, favored treatment is "we get to watch the world cup". And well, the perceived superiority is just obvious. I guess maybe you don't know what elitist means because that was a perfectly appropriate time to use it.
