CBS late-night host Stephen Colbert unleashed a torrent of vulgar insults at President Trump on Monday, including saying Trump's mouth was only good for "being Vladimir Putin's cock holster."

After Trump's occasionally contentious interview with CBS political director John Dickerson aired, which included Trump quipping that he called Dickerson's Sunday CBS program "Deface The Nation," Colbert was in high dudgeon.

To the delight of his "Late Show" audience, Colbert reeled off a series of "burns," as the Daily Beast put it.

"Mr. Trump, I love your presidency, I call it ‘Disgrace the Nation,'" Colbert said. "You're not the POTUS, you're the ‘bloat-us.' You're the glutton with the button. You're a regular ‘Gorge Washington.' You're the presi-dunce but you're turning into a real prick-tator."

"Sir, you attract more skinheads than free Rogaine," Colbert went on. "You have more people marching against you than cancer. You talk like a sign-language gorilla who got hit in the head. In fact, the only thing your mouth is good for is being Vladimir Putin's cock holster."

Holding up his pinky finger in a clear reference to Trump's private parts, Colbert concluded, "The only thing smaller than your hands is your tax returns, and you can take that any way you want."

Colbert's penchant for vulgarity has not stopped with Trump. Referring to Vice President Mike Pence's quote during a debate that he tries to "spend a little time on my knees every day," Colbert joked last year that showed Pence was "very close" with Putin.

"Now, fair warning, Mike," he said. "Indiana businesses can refuse to serve you, and it's your law. It's your law."
