As hip-hop has grown, co-opting flows has become far more common.

Calling rappers out for biting flows is a touchy subject and can end up in violence. On October 21, during the Rolling Loud festival in Northern California, A Boogie wit da Hoodie and PNB Rock allegedly jumped Lil B. The altercation likely stemmed from two tweets Lil B tweet sent on September 30th saying:

Lil B forgave A Boogie & PNB Rock immediately and they have since squashed their beef. However, B’s tweet highlights an intense debate in hip-hop: Is it okay for a flow to be co-opted by another artist?

Meanwhile, Cardi B, whose currently enjoying the success of her hit “Bodak Yellow,” used Kodak Black’s flow from “No Flockin” to rise to the top of the charts.
