In hip-hop, not much is off limits in regards to grounds for igniting a rap beef, including the age-old debate of who "did it first."

Earlier today (Dec. 15), Kodak Black had some fighting words for Lil Yachty and D.R.A.M., claiming that he was the first to use the word "broccoli" as slang for marijuana and that the two rappers' chart-topping single by the same name "jocked his swag."

After Lil Yachty expressed his anger, E-40 got wind of the ridiculous nature of the argument and had to lay down the law STAT.

E-40 promptly took to his Instagram account to remind Kodak Black, Lil Yachty and D.R.A.M. that he used the slang word before some of them were even born.

"In 1993 I refer weed as BROCCOLI on my song 'Practice Looking Hard,'" the rapper captioned his Instagram post. "In 1998 I made a song called 'BROCCOLI' On my Gold double album 'The Element of Surprise' #PROBLEMSOLVED #BROCCOLI F**k beef get money!"

Yup, problem solved. 

During the video, E-40 pays special mind to a specific line, shutting down the argument once and for all.

The bar reads, "Got me a baggy full of broccoli and a crooked Ides 22/I feel great, I'm mean muggin', but I feel great."

Additionally, the veteran rapper also once explained the lyric to Genius, detailing how he was inspired to use broccoli, as well as lettuce, to refer to marijuana. 

Sorry, fellas. Case closed.

Take a look at E-40 shutting down another beef that no one asked for in the Instagram clip below.
