Oh, and, possibly surprisingly, if you can handle the noise and close people, football fan sections can be good.
They will tell you what to dress and how to behave, when to show up, teach you the words of the songs. My experience is that if you show up and actually do the thing for 90 minutes, they'll let you in. It's clear what to do (the capo tells you), you know when to cheer and boo (everyone around you will be), there are flags and scarves (and eventually pyro and audio stuff if you go deep) to fiddle with, they always need more drummers, and everybody knows when it's time to go home.
My friend with social anxiety loves it, that environment just wipes everything he normally hates about get togethers right off the table.
Plus, if you're a memorizer, you'll be around people who think it's awesome that you remember what number the homegrown substitute left back from eight years ago wore on his national team appearance.
Watching the game is fun too, but optional.
