Michael Rappaport sues Barstool Sports for breach of contract and allegedly ...

Michael Rapaport is suing Barstool Sports, its president and two on-air personalities, alleging defamation for tweets and a tee shirt design that he said imply that he has herpes.

Rapaport, 48, who used to work with the company, was fired in February after tweeting an insult at a super fan of the site, saying those who call themselves 'stoolies' have 'already lost in life.'

Barstool Sports' president David Portnoy responded in a statement to TMZ, calling Rapaport 'an unhinged lunatic.'

'Michael Rapaport is a loser,' Portnoy said. 'There is nothing worse than somebody who claims to be the king of trash talk and then cries when people respond in kind.' 

Portnoy is personally named in the lawsuit, along with staff members, Adam Smith ('Smitty') and Kevin Clancy ('KFC').

Rapaport's lawsuit claims Barstool Sports staff called him a 'herpe having, race baiting, D-list actor' and 'old crusty herpe.'

He alleges this amounts to defamation because he 'does not suffer from herpes,' and Rapaport is seeking unspecified damages on that claim. 

The lawsuit also includes a breach of contract claim, asserting that his firing was unlawful. Rapaport claims that Barstool failed to pay him 'hundreds of thousands of dollars' that he said is owed to him, TMZ reported.

Rapaport hosted his popular podcast, 'I Am Rapaport,' under the Barstool Sports brand up until February.

He was promptly fired following an exchange he had with a fan of the site who called him out after Rapaport got into an online feud with another employee, who goes by 'Smitty.'

Rapaport was questioning whether Smitty was on performance enhancing drugs when he won a boxing match against Shaun Latham, also known as '$20 Chef.'

He tweeted some derivative of, 'Ask @SmittyBarstool if he’s on JUICE right he loves talking to his "fans,"' a total of 91 times during and after the February 16 event, according to a recap by Barstool Sports.

To one of those tweets, Smitty replied to Rapaport:

'Jesus Christ you're a loser. I'm done with losers. Ask LPres. Now pay me my $2K fantasy football money you owe me you fraud.'
