for complications caused by sickle cell anemia. Legacy Mobb Deep helped popularize the 1990s slang called the "Dunn language," a term first recorded in the 1999 single "Quiet Storm," in which Prodigy raps: "you's a dick blower, [you] tryin' to speak the Dunn Language?/ "what's the drilly" with that though? "It aint bangin"/ you hooked on Mobb phonics, Infamous 'bonics." The term "dunn" supposedly originated in the Queensbridge housing projects with an acquaintance of Prodigy's, Bumpy, whose speech impediment prevented him from pronouncing the letter "S," such as in "son." The impediment encouraged him to put the tongue on the two front teeth/palate, making a 'th' or a 'd' sound. Mobb Deep has attempted to claim ownership of this body of slang; additionally, they were going to release an album called The Dunn Language, in 2002, but the project was shelved, due to label issues. On September 15, 2018, during an interview for HipHop4Real, Havoc stated that he was working on a new album Mobb Deep, which would be the duo's latest album. He is also working on a joint project Mobb Deep with The Alchemist, announced a few years ago. In December 2019, Havoc went on a "Murda Muzik 20th Anniversary Tour" with Big Noyd and L.E.S.
