Genuinely seems like a bit of a bit of fun at a nothing match inspired by an unlikely Ameobi's bruv's goal. They are even shaking hands with Darlington players on the pitch.
And, as Mark says, if the bloke (presumably a Newcastle fan) punched a female steward, then getting a good kicking from (presumably Newcastle) fans is commendable retribution.
Don't let the truth get in the way of bit of Toon bashing....
...I do actually mean that.
