@Solius nailed it with that template, it's downright bloody bizarre.
I live in Manchester and I'm in the city centre every single day, and not once have I had such interactions with any City fans. I've met and worked with plenty of the years and never has any hint of violence or insults/abuse arisen.
Why do they (bluemooners) feel like they have to act "ded ard" all the time? Surely with them making this stuff up they kind of know that everyone else is making their stupid stories up too, and it's only each other who's buying it. It's like that episode of Archer where Lana lets every guy pretend to have fecked her and even though they all know it's bullshit they play along with it.
