South African women have taken to Twitter to show off their assets and flexibility as they took part in a viral challenge.
The Vuthela Challenge sees women with big backsides showing off what they’ve got.
The women kneel beside a pot and pretend to be blowing on the fire, though their backside is the main focus.
A number of women have shared photos of themselves taking part in the challenge and the men have decided on their winner.
