This is the eye-watering moment a man dislocates his arm while receiving a 'bum beating' from an exotic dancer at a show in Brazil.
The footage, taken at the performance of DJ Meury in Monte Alegre, Brazil, on June 10, shows thick-thighed dancer Camila Silva holding her calves around a man while balancing on the stage with her hands.
In the video, Ms Silva then slams the man's face into her buttocks and bends one of his arms at a seemingly impossible angle.
The volunteer then remains lying in discomfort on the stage as a member of staff rushes over to check on his injury.
Known locally as 'surra de bunda', the bizarre dance move - allegedly invented by the Brazilian group Tequileiras do Funk - is often performed on male audience members at 'favela funk' parties.
