*Stereotypical hat on* Let me tell you something, I just want to say! *Points for those who get reference*
The one I run into as I'm such a big supporter (Vamos United!) is Association Football, which English nicknamed Soccer in same way Rugby Football was nicknamed Rugger. The US called this sport football for decades, but around 60s or so changed over nickname as official name as USFF became USSF (I guess to avoid confusion with sport derived from Rugby called Football or American Football).
Not that any of it matters, lived, visited and have many friends from the UK. Good folks.
