I think I heard this on the podcast once so can't take full credit.Their plastic "ultras" are quite embarrassing.
Screaming pre recorded chants into a microphone, jumping up and down for 30 seconds before the next regimented sing along to the exact same tune over and over again.
But Palace Ultras, all a bit Father's For Justice.
Like if you rocked up to a match dressed as batman it probably wouldn't even be that weird.
