Box
Heard in Sligo, Galway, Tipperary, Dublin and Waterford
A punch. If a person of questionable upbringing is in one's face, an appropriate phrase to remove them from one's presence might be,
Feck off or I'll box de feckin' head off ya!
Kindly remove yourself from my vicinity, or I shall be forced to land a most severe blow upon your countenance!
