that is the sign that you are rank 10 (i think, maybe it was 12). you get ranks when you gain a certain amount of Fame in the tournament (Tomb of the Primeval Kings). it takes a hell of a long time to get the tiger /rank emote.
I also just found they were rank emotes in game. I did alot of searching, but didn't know what I was searching for, so didn't get anything back about them.
