Farrah's Boyfriend Just Called Pregnant Kail 'Shamu' & It's NOT OK

Here we are again, another Teen Mom feud for the books! Teen Mom OG star Farrah Abraham's on-again, off-again boyfriend, Simon Saran, and Teen Mom 2 star Kailyn Lowry exchanged some HEATED and very personal words via social media, which all started over Farrah's mini horse, Starburst. Click through for the play by play of this nasty showdown!

Both Farrah and Simon were promoting her newest #MomBoss clothing line, and a fan asked if the proceeds would be going towards freeing her mini horse, Starburst. Simon replied, "Stop being a hater. Go protest at a zoo or sea world."

And this is where Kail is brought into the conversation! The fan replied back asking, "Sea World is at @KailLowry 's house, right?" Ouch. And Simon replied, "Sure if you are looking to free Shamu." Low-blow!

Kail fired right back at Simon, bringing up Farrah's lady parts.

And Farrah's man fired back, bringing up Kail's third baby daddy. She is expecting her third child with Chris Lopez this summer.

As loyal Kail fans may know, Chris and her are no longer together and she has been open about how she will be raising her third baby as a single mother from the beginning, hinting that Chris will not be a part of the unborn child's life.

But meanwhile, the feud continued to get uglier ...

... and uglier!

Farrah, however, remained quiet as Simon was at war with Kail.
