In "Bully in the Alley" who's Bob?
So for context I recently heard the shanty "Bully in the alley" in it the chorus goes "Help me Bob, I'm bully in the alley wey hey bully in the alley X2 in the alley of Shangri-la" my question is is there any significance to who Bob is or is it just needed a one syllable name? I know the song is literally about being drunk and your mates leaving you passed out in the alleyway but I was wondering "Who the heck is Bob? " Both joke answers and real ones accepted.
