Seems like XXXTENTACION has been calling out the rap world since he came out of prison. The "Look At Me" rapper has taken his attention off Drake for a moment to attack Rob $tone. He even said "Chill Bill" was wack.

In a recent IG Live clip, the effervescent emcee clowned $tone's platinum hit saying, "Listen to this shit, you got niggas whistling on your shit. What the fuck." Other people in X's video laughed while he mocked "Chill Bill." 

What has prompted the Florida rapper's rant was an incident that occurred Sunday at Desiigner's show in $tone's hometown of San Diego. XXL reports that $tone was given a mic to perform while Ski Mask The Slump God, another opener for the event, wasn't. X and Ski Mask are friends and worked on the new track "Bowser" together.

Upset, Ski Mask tried to grab a mic according to a fan. He then stood in the middle of the stage while $tone's set was starting. The matter was settled when Ski Mask got escorted off the stage.

Or so people thought. X said he rifled through $tone's photos and found out that "that nigga as little as fuck." He says Ski will "whoop that nigga ass." Rob $tone responded in kind.

Ski Mask answered that he wasn't at fault.

The touring rappers will have to bury the hatchet though; Ski Mask and Rob $tone have 20 more dates to go on tour. Check out more clips below.
