Pusha T and Arby’s continue their collaboration with a new diss track aimed at McDonald’s.

The track is titled “Rib Roast,” which celebrates the return of Arby’s REAL Country-Style Rib Sandwich — namedropping and putting to shame the McDonald’s McRib as King Push criticizes the fast food chain competitor for serving mystery meat. The rapper boasts of Arby’s Texas pit-smoked “country-style” pork rib, which is offered with crispy onions, melted natural cheddar cheese and smoky BBQ sauce on a toasted star top bun.

In addition to the new diss track, Pusha T and Arby’s dropped a limited-edition “country-style” merch honoring the menu item’s roots. The collection features a custom Pusha T T-shirt and jacket with Arby’s Ten Gallon Hat logo, a sandwich bolo tie, trucker hat and bandana.

“We are on a mission to call out weak sandwiches of questionable quality, and there is no other product that can compare to our REAL Country-Style Rib Sandwich or is worthy of Pusha T’s praise,” Jim Taylor, President of Arby’s, said in a statement. “We’ve spent years perfecting the intricate smoked rib flavors and are proud to have Pusha remind people why Arby’s has the meats – and smokes the competition.”

“Rap Album of the year. Sandwich of the year. Simple as that — we both give you quality straight from the kitchen!” King Push added. “I love the work I’ve been doing with Arby’s — this time around we have to chef up something different and give everyone quality country inspired merch to go along with the rib sandwich.”
