I've always liked this song, but have no clue as to what, if anything, it means. Anyone know what kind of flag we're talking about? What's a flag boy? Is there any significance to the king, or is it just a variation of "man"? And "iko iko", "jock-a-mo", etc.--nonsense syllables? Gullah? A distortion of Gullah or of some other language?

If anyone can shed some light on this, I'd be grateful.
