means The sport in which two teams of eleven try to kick a ball into each other's goals without using their hands, known as football almost everywhere except the places that invented the word 'soccer.'

from Surprisingly, 'soccer' is British, not American. In 1860s England the game was formalized as 'association football' to distinguish it from rugby football. Students at Oxford had a slang habit of clipping words and adding '-er' (rugby became 'rugger'), so 'association' was trimmed to 'assoc' and then to 'soccer.' The word later flourished in America and Australia while fading in Britain, which is why the British now treat it as an Americanism they didn't actually start — though that origin is well documented.
