Your style is played out
Like Arnold and that, what you talkin' bout Willis
from The Notorious B.I.G. (Ft. Method Man) – The What Lyrics on Rap Genius
Meaning
A celebrated line, oft-repeated by Gary Coleman’s character on the t.v. show Diff'rent Strokes

As with Arnold’s line, Biggie finds other rappers' verses full of tired old phrases, “played out” (rendered banal) by repetition
See the Flava In Ya Ear (Remix) for another Diff'rent Strokes based simile from Biggie.
