Cortney Casey and Felice Herrig give each other the middle finger in the middle of their UFC 218 fight

Felice Herrig roared as he secured her fourth straight UFC victory against Cortney Casey in a split decision win in Detroit.

The two fought out a close encounter that was interrupted at times by the two strawweights flipping each off mid-fight.

It was an entertaining moment for the fans as the two women channeled their inner Nate Diaz, a fighter who loves to rile his opponents with the middle finger.
