One unfortunate patient found out the hard way why you shouldn’t wear metal during an MRI after a butt plug they were using shot through their body.

A post on Twitter that appeared to show a scan of a butt plug that caused “major injuries” lodged high up in someone’s body as a result of an MRI scan has gone viral, undoubtedly making many people clench in the process.

In the post by Twitter user @BradiusZero, he explained why you should “Never wear a butt plug to your MRI appointment” and shared an image of a scan that appeared to show a butt plug lodged in a person's chest cavity.

Alonside the image, a separate text message read: “Greatest personal injury case I've ever heard. An estimated Valley attorney, has picked up a client who is suing a sex toy company. Said client purchased a butt plug that was advertised as ‘100 percent silicone’. Client wears butt plug to MRI appointment.

“Much to client's dismay, butt plug in fact has a metallic core. Butt plug is accelerated at the speed of sound…into client's chest cavity. Described in memo as an ‘anal rail gun’. Client survived with major injuries.”

The post has been viewed 10.8 million times with many speculating on what was going on there.

One person tweeted: “I’m glad they’re alive but I can’t help but think that the patient was trying to intentionally shock the doctors upon doing the MRI scan as a joke and it went horribly wrong.”

Wearing metal in an MRI can be dangerous due to the magnetic force that is created by the machines which is approximately 1,000 times stronger than a typical fridge magnet.
