In the clip, you see one of them on board a jet ski, asking her friend to get a photo of her.
Her mate, sporting nothing more than a bikini, starts to line up the picture, before something bizarre happens.
Out of nowhere, another duo on a jet ski enter the shot and slam straight into the posing woman's vehicle.
They are sent flying through the air and make brutal contact with the sand.
DISASTER: The accident could have been a lot worse
Both the passengers appear unharmed as they manage to get back to their feet.
The woman who was patiently waiting for her photoshoot is not impressed though, as she looks round in disappointment.
It is unclear where and when the clip was filmed, but it has gained popularity today after being shared on Reddit.
Posted in subreddit wellthatsucks, it has racked up more than 23,000 hits.
And viewers loved it.
One comment read: “I just can’t stop laughing. This has to be one of my favourite videos I’ve seen.”
And another added: "She literally just casually walks away. Like 'Damn it, you’re ruining my Instagram shoot.”
