The song's title is an acronym for Khalifa Kush, a strain of marijuana sold by the San Jose, California dispenser The Cookie Company. The enterprising, weed-loving Wiz allowed the company to name the reefer after him in exchange for an unlimited free supply, which sounds like a good deal for the rapper.
He brags about this arrangement on this track when he spits: "I got my own weed sucka, so I ain't gotta hit yours."
Both Juicy J and Project Pat also contributed to the tune.
Until December 5, 1998, a song had to be issued as a single to make the Hot 100. Aaliyah's "Try Again" was the first tune to top the chart based on airplay alone, without any sales figures being included.
