@MrPan - Well that's your interpretation. I know it differently. Yes it was a non-Dublin folk reference but times change. It's far more generic and yes it's accurate for Johnson.
That would be the interpretation of every Irish person I know. And, as I'm Irish, living in Ireland, that would be a fair few people.
Bog trotter? I was being specific to an Irish context. It's an assessment for an ignorant oaf
If you were being specific to an Irish context, then I would assume you were referring to the Irish meaning, which is not an "ignorant oaf". It may be far more generic in the UK, but it isn't in Ireland.
