Stormy Daniels' Description of Trump's Penis Is Making 'Mario Kart' Fans Sick

"Mario Kart" is trending for all the wrong reasons on Tuesday, and is grossing people out once they figure out why it's the talk of Twitter.

It has to do with Stormy Daniels, Donald Trump and the president's penis. Last chance to back out in case your stomach can't handle it.

Still with us? Okay, you pervert, here's the deal: The Guardian obtained an excerpt of Daniels' new memoir, "Full Disclosure," in which she compares Trump's "unusual" penis to a character from the popular Nintendo game.

"He knows he has an unusual penis," Daniels reportedly wrote. "It has a huge mushroom head. Like a toadstool ..."

"I lay there, annoyed that I was getting f--ked by a guy with Yeti pubes and a dick like the mushroom character in 'Mario Kart,'" she added.

According to the Guardian, salacious details also include her summation of his penis size: "smaller than average," but "not freakishly small."

"It may have been the least impressive sex I'd ever had, but clearly, he didn't share that opinion," she wrote of her alleged tryst with Trump at a celebrity golf tournament in Lake Tahoe, California, in 2006.

Twitter is now collectively trying to cope with the trauma of having that visual of the First Penis stuck in their head. Enjoy everyone else's pain below as you try to numb yours.
