My take on this situation is that yes, I can understand you want to have fun. But rdming another staff member, one creates a bad impression and if they don't agree, its even worse. The fact that you did this after being told to stop doesn't help your case. You need to learn how to take criticism.
You were also acting very immature, and i don't know if this was a reason for your official. But you were being very disrespectful and annoying to myself and other lead-team members.
In my opinion, this was justified. You are going to need to improve your attitude and learn to follow the rules, even if you are just messing around for "banter".
