Do these bananas have any idea who they on the planet with?
Apes, yeah you bananas to the grapes
Lupe is questioning whether other rappers know who they are dealing with. He is the apex predator and they are just a food source.
There is also wordplay around bananas. a primary food source for apes, hence effecting a reference to the movie Planet Of The Apes
Whack rappers (Kendrick in this case) are bananas (as in crazy) and grapes (small, inferior, squashed under one’s feet to produce juices)
The bananas and grapes can be seen as a parallel to “apples and oranges”.. they are not the same.
Lu pronounces “grapes” to sound like “greats”, which given the context of this line makes a lot of sense. The greats possibly being those Kendrick compared himself to. The greats/apes literally eat bananas.
