Seemingly X-rated optical illusion sends Reddit users into a frenzy

This optical illusion is causing a stir online, but it’s not what you think it is. Take a closer look.

A Reddit user has been left seeking reassurances that he isn’t the only one with a dirty mind after an innocent photo was shared online.

The dubious image created a rather unfortunate shape as viewers were all left thinking the same rude thing.

The X-rated illusion was reposted from Twitter in the subreddit Optical Illusions, The Sun reports.

And the unique snap, showing two muscular legs next to each other, racked up numerous interactions as others had their say on the naughty pic.

One wrote: “Those legs are muscly wtf,” as a second added, “lol took me a second.”

A third user put it plainly for those who didn’t see it at first penning: “Many people see a fit naked couple standing up behind the other, but it’s just muscly legs crossed at the ankles.”

It’s not the first time an X-rated optical illusion has caused a storm online.

A couple’s cute photo had also gone viral. The image shows a couple relaxing on a boat in the sunshine.

But bizarrely, at first glance it appears as if the man in the picture is naked.

“At first, in the thumbnail I thought he was totally naked. Then I realised that was his hand,” a Reddit user wrote.

“Then I clicked it and realised it was her legs. Then I went back to the thumbnail, and I thought they must’ve done that intentionally.

“Then I clicked it again and realised they didn’t. This post has been an absolute emotional rollercoaster for me.”

Professor Cedric van den Berg, from the University of Queensland, explained that illusions are simply a trick that our brain plays on us while trying to “fill in the blanks.”

“Our eyes and brain speak to each other in a very simple language, like a child who doesn’t know many words,” he told Newsweek.

“Most of the time that’s not a problem and our brain is able to understand what the eyes tell it.”

“Optical illusions happen when our brain and eyes try to speak to each other in simple language, but the interpretation gets a bit mixed-up.”
