Young Thug and YFN Lucci got into an intense back-and-forth via Instagram Thursday night.

What appears to have kicked things off again between the two, who have publicly exchanged words before, was some comments from Thugger during an Instagram Live session. During the stream, Thugger said "of course" he was going to slap Lucci and Sauce Walka. "I'mma slap the hell out y'all little n****s, man," he said. "Stop playin' with me."

From there, Lucci responded via his Instagram Story with a gay slur and said Thugger wouldn't be slapping anyone. Sauce Walka, meanwhile, has shared footage of Thugger with a boxing trainer:

Thugger then responded to Lucci, reiterating that he intended to slap him the next time he sees him in public. "My teeth cost more than your little broke ass life, boy," he said in a Story update. "Stop playing. I'mma slap the shit out of [you] as soon as I see you, like I said."

Lucci later tagged @okaykarlae (a.k.a. Thugger's girlfriend Jerrika Karlae) in another update, saying "Ya husband ain't nun."

The issues between the two have been ongoing for several years. Back in 2017, for example, Thugger and Lucci got into it after Thugger declared himself the new 2Pac. "Pac would've never wore a dress," Lucci said at the time, to which Thugger indirectly responded in a series of tweets advising that "doin [too] much could become a deep sleep."

Both Thugger and Lucci were among the assembled guest artists for T.I.'s 2018 album Dime Trap, which dropped back in October.
