I kick it like Nike they’ll soon adjust to it
Clever double entendre. Joey is saying he kicks it (hangs/chills/) like Nike, a company famous for its shoes (also called kicks).
In the second half of the line, he’s basically saying that people will “adjust to it,” with the “it” referring to his style/the way he is. These words sound very similar to Nike’s famous slogan, “Just do it.”
Or he could be going a subliminal route. When you buy a new pair of shoes, they usually are a little tight, but with time you get adjusted to it.
His raps are similar. At first, you will be a little wary of his style, since it goes against the mainstream, but after a while (“Gotta give ‘em time to listen”) you will be a fan too.
