Last month, Michael Cohen, Trump’s former lawyer, promised that his new book would contain “graphic and unflattering details” about his ex-boss. It turns out he wasn’t lying.

On Thursday, Cohen posted the foreword from his forthcoming book, Disloyal: The True Story of the Personal Attorney to President Donald J. Trump, on a website for the book. One passage in particular set social media aflame: “From golden showers in a sex club in Vegas, to tax fraud, to deals with corrupt officials from the former Soviet Union, to catch and kill conspiracies to silence Trump’s clandestine lovers, I wasn’t just a witness to the president’s rise—I was an active and eager participant.”

“Golden showers” is a reference to a sex act involving urination. Shortly after that passage was highlighted by Twitter users, the hashtag #UrineTroubleTrump began trending on the social media site.

Cohen’s book is being published by Skyhorse, but isn’t listed on Amazon or Barnes Noble. The book is available for pre-order on his website, as a hardcover copy and as an autographed edition, the latter of which he’s selling for $40.

Cohen has claimed that the Trump administration tried to stop him from publishing the book, and he says as much in the book’s foreword, writing, “One last thing I can say with great confidence, as you turn the page and meet the real real Donald Trump for the first time: This is a book the President of the United States does not want you to read.”
