Boosie is still not happy with NBA Youngboy...

The two were once close, but the relationship went sour and the two found themselves dissing each other on records.

Now, in a new interview with DJ Vlad, Boosie explains why he went in on Youngboy, and it's pretty simple. 

Boosie says he dissed him on record because he didn't want to kill him., and that Youngboy was on some "p***y sh*t".

He went on to say that he wouldn't pick up his phone call, and he doesn't want to talk to him.

Peep the full clip below.

"Cause I don't want kill him," Boosie said when Vlad asked why he dropped a diss track on YoungBoy.  "I just wanted to say what I had to say.  I didn't really promote the song.  I just felt like I say what I was going say on the mic and that's it."
