Rapper's Navigation Skill

Okay, so listen up, genius. You see, rappers are musicians who rap, right? And "flow" is like, their rhythm and style. But "flow" also means, like, a river's flow. So the joke is that they always have a "sick flow" (good music) to follow, so they don't get lost. You probably think flow is when you go to the toilet. I bet you do not even know how to write. Based.
