Some people say you don’t truly hold the championship belt until you have defended it. By any standard, Joanna Jedrzejczyk is a UFC champion, and her fan base grew Saturday in Berlin as she systematically battered Jessica Penne, stopping the challenger in just under three rounds.

As always, Twitter reacted.

And here comes the champ. She walks to “Przejmij Ster w Swoje D?onie” by Rena feat. Gutek. (Translates to “take the helm in his hands.”)

Not sure what it’d look like if you stuck an M-80 up someone’s nose, but I’m guessing Penne is giving us a preview.
