I'm from Yorkshire and the late 90s were unbearable. I can honestly say they are the most vulgar fans. They take pride in hooliganism and use it as some sort of medal of honour. They are the first to laugh at you when your team gets beat and they have no shame in how bad there's is in comparison. Most of them don't actually talk about the football, it's more about the violence or being able to laugh at rival fans. I remember being in a bar with some old friends I used to hang out with, watching us vs arsenal when jol vs Wenger happened and one of my pals (Leeds fan) was jumping up and dow and screaming in my face when arsenal scored. I asked him later on "Why behave like that? You don't support arsenal" his response "I just wanted to piss you off", which considering I'm mild mannered and celebrate in a controlled manner was ridiculous. But that's Leeds fans for you.
