Cyborg uses 'Running Man Challenge' to call out Rousey

Until Ronda Rousey agrees to a fight, Cris "Cyborg" Santos is going to continue having fun at her rival's expense.

Cyborg has repeatedly accused Rousey of running away from her and now she's punctuated that point with a less-than-subtle use of the popular "Running Man Challenge."

In the video above, Cyborg and her plucky sidekick don Rousey masks before getting down to the viral tune to mock the former UFC women's bantamweight champion.
