What's soccer? Is that where you put socks on cars? We're talking about a sport played with a ball and feet. The fact you weirdos confuse it with handegg is your own problem.
There are at least half a dozen different games called "football," none of which are the One True Football(TM). Soccer is a shortening of Association Football (itself named to differentiate it from Rugby Football which was codified earlier), and was, in fact, used as slang shortly after the codification of Assocation Football around 150 years ago.
You can identify the condescending assholes that already know that because they use terms like "handegg" to feign ignorance of this when they demand you stop using a word that's been in use for a century and a half in favor of their preferred terminology.
