There a many theories on this video.
Most of them are:
She must’ve hit “The Predator”
However the most likely came from the following commenters:
Her foot got caught in the rope that’s used to bring the handle back to the platform?
Right between her legs almost into her snatch!!!! Rode it like a cowboy & got thrown off, excuse me, flipped off!
But I think, “Yep, probably The Predator”. -Rick
