Sipping on that syrup 'til I'm messed up like yes sir
Obviously, Rocky isn’t a character a known to be polite as he reveals later on in the song(Going wild for the night Fuck being polite.) Saying “yes sir” to someone is being polite so in order for Rocky to be that polite he would have to be really high. Also, “syrup” is codeine cough syup, a drug widely known in the rap culture.
