And I quote, as posted on their Facebook page over the weekend:
"We have announced today that Black Desert Online will get special butt pose victory animations in the new Crimson Battlefield PvP mode, which was added as part of the Mediah Expansion earlier this week.
"The Crimson Battlefield is an instanced 40v40 PvP mode which can be entered in groups of five or individually. When players emerge victorious, their characters will flaunt their buttocks right before the end results screen appears. The new animations are unique to each class and will be available to both genders."
The first series of butt pose animations will be added during next week's maintenance and will be made available at no additional cost. A wider range of optional butt pose animations will be made available through the cash shop at a later stage."
