Unfortunately I have seen many instances of fight winners embarrassing themselves to the extreme in similar ways.
Why can't fighters be more humble these days?
"Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win."

What about when Cristiane "Cyborg" Santos ran and jumped on the cage and celebrated her win while her opponent was getting back up and recovering because the fight was never stopped. She beat her down then got all exited, the ref never stepped in and it actually took her alot of convincing to get her to fight again. She really didn't understand when the ref was like "no no its not over get ready to fight".
