Even though he’s still in prison, C-Murder’s been able to release music steadily over the years and today we get another offering from him. And it’s a little more vicious than normal.

“2 Stainz,” now available on iTunes, pretty much describes itself as Master P’s brother decided to take aim at 2 Chainz by claiming he was the one who founded the TRU movement.

“I made this TRU s**t 2 Chainz, f**k you n***a, p***y a** n***a," he raps in the song, "Ya d**k in the booty a** n***a, you’d be a h* if you was in the pen."

But wait, there’s more. Murder threatens the rapper formerly known as Tity Boi with violence and says he’s the greatest to ever come from TRU.

“I’m the realest n***a that ever wore a TRU chain,” he continued. “This goes out to that b***h n***a 2 Chainz / You could never be me ’cause ya too lame / I pop ya in the chest and make 2 stainz." Geez.

2 Chainz didn’t seemed to be too phased by the diss. He took to Instagram after the song dropped and replied, "My partner just notified me that C-Murder made a diss song about me," he said while smoking in the dark. "That's hard as fuck. C-Murder always been hard as fuck. TRU." He then posted a subsequent video singing to Marvin Gaye's “You Are Everything.”

This isn’t the first time C-Murder has dissed an associate. He even took a shot at Master P on “All I Wanted 2 Be Was a Soldier” in September 2014.
