CK Rules!
From AmtWiki
From The Stick Jock's Dictionary - Transitioned from Wardancer Behind. Different kingdoms have conflicting views on how appropriate it is to flank or backstab the opposing team during ditch battles. The CK perhaps influenced by members of the Chosen indulges in this tactic as a matter of course. Other players including members belonging to the Emerald Hills disapprove strongly of the tactic. Some of them can be very vocal in their criticism. As a result “CK Rules!” is the battle cry used by members of the Celestial Kingdom when running the flank at IK events or in the Hills proper. It has a double entendre
1) that we are playing by the rules as they are understood by citizens of the Celestial Kingdom and
2) CK players in fact rule.
