50 Cent and Rick Ross are probably not sending each other Christmas cards this year, having subjected each other to considerable amounts of public humiliation. The feud dates back several years, but it finally hit court in 2015. This July, 50 was ordered to pay $5 million to a woman named Lavonia Leviston after it was determined that the rapper inflicted emotional distress on her by hosting a sex tape featuring Leviston on his website. That ruling led the G-Unit general to file for bankruptcy protection, a move he claimed was purely strategic; Ross nevertheless mocked him for it on social media. Now, the two heavyweights are once again going at each other over apps.

It began with 50 Cent hawking comically cheap ($2.50) shirts designed to make the wearer look like a shirtless Ross, complete with all the excess weight the Miami star has since shed. Before too long, Ross saw 50's post and retaliated, screenshotting the original and mocking him for effectively selling Maybach Music Group merch. (Ever the shrewd marketer, Ross even found a way to bring the conversation back around to the title of his forthcoming eighth album, Black Market.)

The two MCs went back and forth with 50 attacking Rozay's credibility and Meek Mill's loss to Drake, and Ross taking it there talking greasy about Fif's son.

Check out the jabs, below.

Earlier this fall, Ross dropped Black Dollar, a mixtape that saw him address, albeit obliquely, the kidnapping and assault charges that are hanging over his head. 50 has mostly stayed on the sidelines with respect to that, though he did throw some jabs at Ross' arrest and that of Diddy, who was booked after allegedly threatening a UCLA football coach.
