VIDEO: This waterslide wipe-out is absolutely brutal

Waterslides are all fun and games, as long as you don't stop sliding.

Because once you stop on a slide – be it intentional or not – you are at risk of all kinds of horrors.

Take, for example, these young women, who appear to have stopped on the slide for a photo op.

But what happens next sent their little slippery sesh viral, with the full video of their sicking collision notching up more than 500,000 views on Streamable since Thursday.

We're unable to find the origin of the video, which was posted to Reddit by SteveV91 on Thursday, so we don't know how badly hurt these sliders were.

We really hope they only copped a few bruises from that crash.

It really didn't sound good, hey?

Like, that noise kind of makes us sick to our stomach.

"It's that dry thump when they crash what does it for me," Redditor SteveV91 said.
