omg you've been to a World Cup game, that is SO COOL. I never have, but I would so want to if I ever get the chance.
My whole American/British English usage is a whole story of its own because I learned British English in school, lived in the US for a while and gravitated towards that, and then I moved home and started doing HP RP and made friends that were mostly of the British persuasion, so I'm like.. a big mesh of terms. And if you then add to it that the direct translation of the terms from Swedish are a mishmash as well (like we'd call a pitch a football field, for example, but we'd say match and not game, and football not soccer) so I'm just a big mess and people like that makes me go "...okay then".
And yes, me too! Football has always been a thing here, but it's interesting to see it happen in countries that have traditionally been more about other sports.
