Manchester United is basically the New York Yankees of the EPL, so not really an affectation, more of a bandwagon thing if you want to get all accusatory and judgy about it.
And I've been an F1 fan since the early 80s, so a little bit before Austin had a track.
I'd say my ironic hipster-style Austin affectation was wearing mesh-back trucker hats (we called 'em "gimme caps" back then 'cause they were all free), but I did it all through the 80s and 90s and never stopped. At least, not until the hipsters started doing it, and it was no longer ironic.
