When Cypress Hill rapper B-Real missed out on a role in the cult classic Friday due to a scheduling conflict he likely had no idea that the missed opportunity would play a small role in his beef with Friday star and rapper Ice Cube.

During an interview with Vlad TV, B-Real revealed that he was unable to star in the film due to a mistake made by his manager at the time and to make up for the mishap he offered to give Ice Cube a record for the movie.

“I wasn’t able to play that so to make it up to Cube because I looked at Cube like one of my fuckin’ homies… I felt bad about it so I said, ‘Aye, I can’t be in the fuckin’ movie. My manager fucked up. I apologize, but you know we’ll give you some music for the movie if you want.’ He was like ‘Oh hell yeah.’ So we made this joint called ‘Roll Em Up, Light Em Up’ and when we had finished the song—we squeezed it in between working on our albums,” B-Real explained. “So we kinda just took time to record that song. When we were done with it we asked Cube to come down and listen to it to make sure that he liked it before we submitted it.”

B-Real went on to explain that Ice Cube approved of “Roll Em Up, Light Em Up,” the song Cypress Hill submitted for the movie. Following Ice Cube’s approval of the song the group went on to play a few songs from the album they were working on at the time including their single “Throw Your Set.”

Ice Cube then asked if he could have the song, but was told the group couldn’t give it away since their label had already expressed interest in “Throw Your Set” as a single. This is ultimately where the groups beef with Ice Cube would begin.

“We took off on tour a number of months later and our homies were calling us from home letting us know, asking us actually, if we had given that ‘Throw Your Set’ song to Ice Cube,” said B-Real. “And we’re like ‘Nah, we didn’t give him that song. What are you talking about?’…We were confused so when we got home I finally heard the song and it was not the same subject matter. He didn’t write about what we wrote about, he wrote about something completely different. But what the chorus was was a variation of what our chorus was…A couple things happened and then eventually it all just snowballed into the beef.”
