Stop acting like the prince [?]
from Kembe X and Alex Wiley (Ft. Alex Wiley, Keenan Coke & Kembe X) – Coke Village Lyrics 1 on Rap Genius
The lyric here is “stop acting like a prince, you’s Semmi”
Keenan indicats that his competitors exaggerate their skills and lifestyle by laying claim to the throne in hip-hop, when they are actually more on the level of servants.
This is a reference to the 1988 Eddie Murphy classic, Coming to America. In the film, Eddie Murphy plays an African prince who visits America with his personal servant Semmi (played by Arsenio Hall) who, at one point in their adventure, claims to be the prince in order to win the affections of an attractive young lady.

Excellent movie. If you haven’t seen it, get on that shit.
