Thread Name: Origins: rathlin bog / Rattlin' Bog / Rattling Bog
Subject: RE: Origins: rathlin bog / Rattlin' Bog / Rattling Bog
My unabridged dictionary says of 'rattling'

1. given to rattling, hence fast
2. Colloquial: fast, speedy, hence remarkable, good, etc

It may be that when the song was new, the phrase 'rattling bog' was humorous in and of itself, because how could a bog rattle? Over the decades we've got used to it.
