Farrah, who has a history of dissing people online has gone after Blac Chyna, posting a racist comment on a video the model posted on Instagram.
"F—kin monkey ewe s—t come up 4 what she is a nothing," the 24-year-old reality star wrote in broken English.
Farrah is known for her reputation as an online troll. Just in the past few months, the MTV star has waged war against Nicki Minaj, Big Brother's Aisleyne Horgan-Wallace, and Kendall Jenner, among others.
Fans of Rob Kardashian's fiancée, 27, however quickly jumped to her defense, bombarding Farrah with comments like, "You are a porn star!! U came from nothing. Thank MTV and god everyday for what you have!"
Blac herself has yet to respond to the racist comment.
