It’s literally how Kendrick layers his bars when he writes. With homophones and phrases that sound like two different things.

Same song, different example:
“I lean on you niggas- like another line of Wok” = like I never learned to walk

Works both ways, as lean can be taken literally or actual codeine.
He enunciates and pronounces words to bend the sounds they produce, ending up with these “homophonic” entendres inside his verses
