In 2015, Young Thug wanted to name a mixtape Carter 6.

It was a way to troll Lil Wayne, who at the time was in a legal fight with Birdman over Carter V.

However, Wayne sicced his lawyer on Thug and Thug ended up naming it Barter 6.

There's supposed to be a Barter 7, but Thugger recently claimed that's been held up because Wayne's legal team is on that, too.

"Lil Wayne trying to sue me for that," Thugger said to a social media fan wondering what's going on with Barter 7.

Do you think Wayne has a case? (And do you think he's really suing Thug?)
