Song: "Hello Brooklyn" (2007)
Album: American Gangster
First Meaning: Jay serves his drugs raw and uncut.
Second Meaning: This is also a reference to Big Daddy Kane's "Ain't No Half-Steppin'."

Complex Says: Kind of a bummer, but Jay actually kinda-sorta used this one of "Fuck All Night" already.

Is It A Double EntendreEnglish Professor Adam Bradley: "This relies upon a homophone—'caine/Kane."
