Cameras capture the scene as the attraction throws riders around, forcing them to cling to the sides or be sent flying.
But for one woman the stakes are even higher, with her trousers retreating down her legs and revealing a bare booty beneath.
In a desperate bid to help, her boyfriend wraps his legs around her, bouncing up and down on her lap as the ride violently vibrates.
Yet it’s of no use and soon the bare-bottomed woman tumbles into the centre of the spinning disk, battling to pull her pants up.
The humiliating scene unfolded on the La Tagada circus ride in Costa Rica – a spinning disk attraction popular with thrillseekers.
It had been set up for the Zapote Festival in San Jose, a traditional end-of-year bash that attracts around 25,000 people each day.
So if the pair were hoping their misfortune would go unnoticed they were straight out of luck, capturing the attention for a crowd of onlookers.
Amid the confusion, one of those watching recorded what was happening and posted the footage online, where it has been seen by thousands of people.
In October, footage emerged of a woman on a fairground attraction in Malta having an unbelievable reaction to the ride – a full-on orgasm.
