Last month, Wack 100 called Nipsey Hussle's hat-wearing homie Cowbowy a snitch for testifying at the trial of Eric Holder, who shot and killed Nip.
Wack also said he believed Holder will do little time for his notorious murder.
Wack has a history of disrespecting Nip's memory.
According to Cowboy, he confronted Wack at the BET Awards and Wack was "turned down" in person.
"When I talked to him he's in it for the Internet sh*t. It's a bag they click on their little pages they make their little money it's all about that. Them n*ggas is turned down ... just leave my dead homie out your mouth and we good. I caught cuz on the way to the car. I had on tennis shoes and shorts, he had a suit. I came there ready to beat up something. I took a photo of him. He knew I had the photo so he had to say something. If I'm a snitch and a snitch take a photo with you, you're supposed to slap the sh*t out of the snitch. But that n*gga was turned down. He was with his family. I could have slapped the n*gga. At the same token, he could have slapped me. But there was nothing extra. There was no need for me to slap this n*gga in public," Cowboy said.
Cowboy added that while he doesn't like how Wack talks, he respects that he goes out in public without security.
