Michael Rapaport's been doing some of his signature ranting on Barstool Sports.

That's not going to happen anymore. On Saturday, the actor and cultural critic insulted the fans of the website, known as "stoolies", accused one of the site's writers of using steroids, and brought up another's marital problems.  He was fired shortly after by Barstool boss Dave Portnoy.

It all started when Rapaport accused Barstool personality Smitty of using performance enhancers before a boxing match. (He's since admitted that he did.) A Stoolie rushed to Smitty's defense and that set Rapaport off.

Portnoy didn't get wind of the Twitter meltdown until Sunday morning. He then fired Rapaport from bed.

Rapaport knocked Portnoy for not changing Barstool's Twitter password, thus allowing him to post another video.

But Portnoy had the last word.

I went from paying you hundreds of thousands of dollars to post videos for us on our main twitter account to having you do it for free in 24 hours. @MichaelRapaport https://t.co/dJWx69mJ5o
