Meaning

Banana clip on the gun!

“Banana clip” is a slang term for a high capacity ammunition magazine, the component of a firearm that feeds cartridges into the chamber. To efficiently fit more ammunition into a magazine (especially single-stacked magazines) the design often implements a certain degree of curvature, making it resemble a banana.

Kendrick previously used this term on “Sing About Me, I’m Dying of Thirst” off his debut major label album good kid, m.A.A.d city.
