Pusha-T wasn't afraid of getting personal on his "Duppy Freestyle" response track, "The Story of Adidon." Throughout the song, he brought several of Drake's close friends and family into the mix.

At one point, he even mocked the current health of Drake's go-to producer Noah "40" Shebib. Pusha raps, "OVO 40, hunched over like he 80, tick, tick, tick / How much time he got? That man is sick, sick, sick."

Shebib was diagnosed with multiple sclerosis in 2005 and has since become an ambassador for the National Multiple Sclerosis Society.

"MS has made me a stronger person and motivated me to find success despite it," he has said of the disease. “MS can’t stop me." Shebib says that he has been able to manage the disease, but he still fears losing motor control in his hands: "I’ve played the piano since I’ve been three, and it’s a really important part of my life."

Shortly after Pusha dropped "The Story of Adidon" on Tuesday evening, Shebib tweeted about the irony of the song being dropped on the eve of World MS Day—which falls on May 30.

Shebib linked to the official World MS Day website, which explains, "World MS Day is officially marked on 30 May each year. Events and campaigns take place throughout the month of May. It brings the global MS community together to share stories, raise awareness and campaign with and for everyone affected by multiple sclerosis. The 2018 campaign will be called #bringinguscloser and the theme is research."

In the past, 40 has expressed his intentions to be a positive role model for young people diagnosed with the disease. He says, "I would like to be visible to young men who might have MS or be diagnosed with it tomorrow, so they know that they are not alone, that they can still succeed and have their dreams." Shebib adds, "By improving connections and knowledge about MS, we can end the disease."
