Too many to list, but;
Many years ago there was a nice PIE ceremony in Amarr in the emperor family station, all the loyalists were there, including our contingent of Khanid Kingdom loyalists. Relationships with the imperials were frosty at best, we had been agitating for Khanid on the throne, squabbling etc. But PIE was nice enough to invite us.
Nice speeches, etc. There was a wardec on by several anti-imperials surrounding the undock and we had been hassling the imperials IC for not undocking while having enemies around while doing their awards ceremony. We got it ooc but being prickly IC was our role.
Anyway they ended up giving away a battleship to a randomly selected guest and one of our KPV members won, unplanned. We quickly decided ooc it was perfect excuse to have a fit, so our guy gets up in front of the assembled and declines the gift and calls all the imperials cowards and we all storm out of the ceremony. We were proper little assholes IC and I was so proud of my antagonistic Khanid corpies playing the hard line unreasonable SOB position.
I know we were a pain in the ass for some of the loyalists back then but I really liked playing the awful prickly Khanid cousins for who had major issues with the imperials...
