Actor Josh Brolin has come out swinging against the new "health" fad known as " perineum sunning."
Last week, an Instagram "healer" went viral for promoting perineum sunning, which is exactly what it sounds like: exposing your anus to the sun.
The Instagram user, Metaphysical Meagan insisted that the practiced is derived from Taoism and promotes health.
So what happened to poor Josh Brolin?
Brolin found out the hard way that it's better to analyze viral social media posts before charging headlong into becoming the butt of an internet fad joke.
