From Byron's Don Juan:
It has a strange quick jar upon the ear,
That cocking of a pistol, when you know
A moment more will bring the sight to bear
Upon your person, twelve yards off, or so;
A gentlemanly distance, not too near,
If you have got a former friend for foe;
But after being fired at once or twice,
The ear becomes more Irish, and less nice.
What is the meaning of this? I looked up the meanings of Irish in Wiktionary, but remained a bit puzzled.
The ear becomes "more filled with anger/passion"? What is "less nice"? Maybe the ear is clipped by the bullet, and becomes malformed?
