What is the meaning of the album title "Flying Microtonal Banana", by King Gizzard and the Lizard Wizard?

The title of the album "Flying Microtonal Banana" comes from the name of Stu Mackenzie's custom yellow guitar, fitted with microtonal frets. The guitar was built to use quarter tone tuning, in which the octave is divided into 24 equal-distanced tones.
