E-40 moves easily across generations and social groups in his new song, "Slappin." Some of my fellas is sober, some of 'em smoking dope, he raps. Some of my fellas is older, some too young to vote. D.R.A.M. provides a hedonistic chorus, and Nef also contributes a verse. The track is slated to appear on the veteran MC's next double album, The D-Boy Diary 1 & 2. Watch the festive video above.
