What is the meaning of the song The Baka Song?

Answer 1

I am not sure if this fits your song but Allied servicemen in the Pacific sometimes referred to Japanese suicide bombers ( air=borne variety) as Baka Bombs or Baka Planes- this being a Japanese word for ( Foolish or in the slang sense- Nuts ) bombs. Never as common as Kamikaze. the Baka planes were purpose built as suicide craft=not adapted fighters or bombers. the Japanese called them Ohka or Oka planes, and euphemistically ( Special assault craft ( I way).
