Luniz is a platinum-selling Oakland rap duo formed by rappers Yukmouth and Numskull. They released an internationally successful hit in 1995 entitled "I Got 5 on It", two versions of which appear on their album Operation Stackola. A third version of the song, featuring Oakland rappers Dru Down, Shock G, Richie Rich, E-40, and Spice 1 and often found on the Internet as the Bay Area Ballas Remix, has also garnered radio play. Luniz were going to be featured on Tupac Shakur's One Nation project. Due to Shakur's death the album was never released.

During Master P's rise to national fame, Luniz attempted to spark a beef over the use of the concept the Ice Cream Man. Due to their waning popularity which was overshadowed by P's skyrocketing exposure, the beef wasn't exploited by the media and they eventually fell into obscurity.

Luniz also had a major beef with Too Short, calling him out on their song "Playa Hata" and saying in the song "thats why the town got rid of Short." This led to an altercation at KMEL Summer Jam in 1996, between Too Short and some posse members of Luniz. Too Short was banned from KMEL radio for a brief period of time as a result of the fight at summer jam.
