‘Mario Kart’ and ‘Toad’ were trending on Twitter Tuesday morning, but for a very unconventional reason that all ties back to Stormy Daniels and President Donald Trump’s penis.

In her new tell-all book, Full Disclosure, Stormy Daniels’ offers graphic details about her alleged affair with Trump.

In one section of the book, she discusses the time Trump’s bodyguard invited her to dinner, which really ended up being an invitation to Trump’s penthouse. She then goes on to say that Trump’s penis was “smaller than average” but “not freakishly small.”

She writes:

“He knows he has an unusual penis. It has a huge mushroom head. Like a toadstool. I lay there, annoyed that I was getting fu**** by a guy with Yeti pubes and a dick like the mushroom character in Mario Kart… it may have been the least impressive sex I’d ever had, but clearly, he didn’t share that opinion.”

By Tuesday morning, the phrase “Mario Kart” was included in over 29,000 tweets, and “Toad” wasn’t far behind with 17,000 mentions. Some joked, “Here I was, innocently thinking a new Mario Kart game had been released.” Others tried to warn fellow Twitter users, writing, “Whatever you do, DO NOT click on the Mario Kart tag.”

Here are some of the top tweets:

It just dawned on me that, at some point this morning, someone is going to have to explain what MARIO KART is to Trump and probably show him pictures of Toad. I would give anything to hear a recording of that conversation. — Scott Wampler™ (@ScottWamplerBMD) September 18, 2018

In her book, Daniels says that she had an affair with Trump during a golf tournament in Californian in 2006; which Trump has denied. She writes that along with a threat he made, he had her sign a $130,000 hush agreement on the night before the election. She is now suing for the contract to be dissolved, arguing that Trump never signed it.

Daniels writes that Trump was never actually interested in becoming president. When former classmates would call her after Trump began to win primary contests in 2016, Daniels says she would respond, “It will never happen… He doesn’t even want to be president.”

At another point in the book, which has bee obtained by The Guardian, Daniels writes that Trump contacted after their meeting at the golf tournament and continued to speak with him because she hoped he would put her on The Apprentice. She writes that Trump said to her, “We’ll figure out a way to get you the challenges beforehand… And we can devise your technique… He was going to have me cheat, and it was 100 percent his idea.”
