AFAIK, it's not a story, it's not lore, it's a song with funny lyrics.

Personally I prefer music without lyrics, since they rarely make sense or matter... the singing is just another instrument to me.

The song is about the singer taking a ship to Jamaica to return to the girl they can't stop thinking about. Spending the whole trip dreaming about her and wanting to get there sooner.

Who Louie Louie is is never clarified. It could be the girl, but could also be the ship or the captain being urged to go faster.
