Rapper NBA Youngboy went off on his own mother on Instagram last week, and he appeared to threaten violence against her on LIVE.

There are rumors online that NBA Youngboy's mom was suggesting that her son was somehow associated with the murder of Baton Rouge rapper Gee Money, who was killed in September 2017. Authorities haven't arrested anyone in that case.

While it has NOT been confirmed that NBA's mom was talking about her son's alleged involvement in a crime, some on social media are suggesting that NBA heard the rumors, and then threatened his mother.

In the video, the rapper calls his mother a b*tch at least a dozen times, as he rants against her "not supporting" him. NBA also claims that his mother never raised him. He claims that he was raised by his grandmother.

In the video he says, "Play with me if you want . . .I'm a do something to somebody."

Listen:

NBA YoungBoy is just 18 years old. And his mother, Sherhonda Gaulden, is 45 years old.

In other NBA YoungBoy news, earlier this month TMZ reported that:

NBA YoungBoy was officially charged in his weed case ... and it could have a serious impact on a separate and ongoing criminal case.

The rapper was charged with 2 misdemeanors -- possession of less than an ounce of marijuana and disorderly conduct -- stemming from a case back in February in Atlanta ... this according to court records obtained by TMZ.

Young Boy was busted along with a female companion, Starr Thigpen, after he allegedly ordered her to get housekeeping out of a room that was supposed to be unoccupied. Starr allegedly struck one of the maids in the face before cops arrived and arrested both of them.
