Usually Albion, but my wife is from the West Midlands and my father-in-law is a West Brom fan. You can see the problem when speaking to him about football.
It depends on who I'm talking to and their cogniscence of supreme football teams.
A 'general fan' of football, or not a follower of the game - I say Brighton . A crapstool polish fan I say "The SEAGULLS" (and call them "The Scum").
A cheaterfield or readung fan, it's definitely "THE CHAMPIONS"
A person who knows me, or an avid fan of anything about English football, I say The Albion .
I'm just an adaptable kind of geezer, me. (or a chameleon kind of lizard, to you )
