Derogatory word Originally used by the British establishment in the US for Irish people. It is an old English slang word for an Irishman. The English also taught the loyalists how to use it. Some say that "mick" comes from the many "Mc" in many Irish names. McKenna, McNeil, McFlannagan, etc.,. Mick is now used between Irish friends and relatives in a playful and joking way of reverse craic. Like " Pat, you stupid mick" While it is derogatory for outsiders to call Irish Diasporadoes it is now commonly used among ourselves. Join THE CAUSE for REAL PEACE with JUSTICE in Ireland, NOW !
