This comes up a lot on here, but to the Mags who post on here: what happens when it's the other way round? When you're slagging Sunderland fans, what do you call Mackems who support Newcastle?
People tend to call them lucky. Doesn't matter to me where a bloke comes from, if he supports my/our team he's OK in my eyes. It has more to do with parenthood than anything else I reckon. If your father supports a team, there's a 99% chance that you will follow the same team.
