They're both the pigs; they call each other it. I'm just not 100% sure who called who it first - that depends on which story you believe.
Isn't it because Hillsborough was built on land that was a piggery? Wednesday fans just started calling utd it because their kit is like bacon. But aye Wednesday originally.
Neither is mine, but Wednesday have been the pigs ever since I've been alive (and thats a long time). SU are the blunts, or just fcking dee-dars - and always have been. Don't know where you've got them as pigs - we've never called them pigs.
It was on Radio Sheffield the other Sunday about this, they reckon it was an old map that was doctored by a Blunts fan and then spread around ! Apparently there has never been any piggery near either ground ! Closest one was 4 miles away !
I though it was from a song one of them you to sing about a player called trotter . Can't remember whether it was united or Wednesday player . Trot trot trot trot trotter score a little goal for me . That's my story anyway
