If you’re keeping a list of things no one asked for, then you can officially add a description of Donald Trump’s penis to the top and you can thank Stormy Daniels.

In her new book, Full Disclosure, which was obtained by The Guardian, Daniels detailed the times she had sex with Trump and included not-so-needed descriptions of his little Donald.

Daniels, who alleged having a one-night stand with The Donald in 2006, said his penis is “smaller than average,” but “not freakishly small.”

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

“I lay there, annoyed that I was getting f—ed by a guy with Yeti pubes and a d—k like the mushroom character in Mario Kart,” she added. “It may have been the least impressive sex I’d ever had, but clearly, he didn’t share that opinion.”

She then added that whenever she saw him on TV afterward, she’d say to herself: “I had sex with that … Eech.”

Daniels' revelation about Trump's penis obviously went viral and caused Mario Kart to trend on Twitter. Those who were eager to find out why the popular game was trending were disappointed and nauseated.
