A comment made by a pearson who has just passed wind to inform those present of the event.
Similar to "more tea vicar".
Joe just passed wind and issued the obligatory good arse comment.

Get the good arse mug.
Used as a way of making others aware of a sighting of a note worthy bum/arse.

More established users of the word may also use it as a way to announce that a night us going well.
A group of lads walking through the streets of Killarney might gaze upon a particularly exquisite female bum, they then look at each other and proclaim “Good Arse!”
