Josh Brolin is sharing some TMI details about where the sun don’t shine… except, in this case, we guess it did.

The actor took to Instagram over the weekend to issue a warning against the viral practice of “perineum sunning,” made famous by Instagram influencer Metaphysical Meagan.

According to the social media star, laying down in the sun, naked, with your legs held up in the air promotes “surges of energy” and “better sleep.” She even suggests that “30 seconds of sunlight on your butthole is the equivalent of a full day of sunlight with your clothes on.”

But it looks like Brolin roasted his buns for a little too long.

Sharing Meagan’s original picture, he wrote: “Tried this perineum sunning that I’ve been hearing about and my suggestion is DO NOT do it as long as I did.”

“My pucker hole is crazy burned and I was going to spend the day shopping with my family and instead I’m icing and using aloe and burn creams because of the severity of the pain,” he explained, adding, “I don’t know who the f**k thought of this stupid s**t but f**k you nonetheless. Seriously.”

Brolin’s burns must not have put him out of commission for too long as he posted a photo with the youngest daughter Westlyn, 1,  just days after trying out “perineum sunning.”
