52 cards come out when I'm through dealing
Now 52 bars come out, now you feel 'em
A deck of playing cards has 52 cards (54 if you count the jokers). This song has 52 bars of rap! (16 per verse X 3 = 48 plus some “intro/outro”)
Like all 52 cards in a deck were handed out, he’s done dealing (drugs).
And of course Jay had a card-dealing sound effect put in after this line.
