Suffering skull-crushing beat-downs from a McDonald’s worker did not stop two crazed women from giving cops and EMT workers an earful, according to police.

“You bitch-ass n- – – – -s!” Denise Darbeau, 24, of Queens, screamed while in custody — despite the cracked skull she’d just suffered.

“I will f- -k you up!” she yelled at cops, while continuing to argue with her sweetheart and co-defendant, Rachel Edwards, 24, of Brooklyn — even as they were strapped to gurneys.

Darbeau and Edwards pleaded not guilty to felony burglary yesterday for allegedly angrily rushing behind the counter of a West Village McDonald’s.
