A policeman's truncheon or baton. Arose from the misconception that the only reason the Irish came to this country was to get drunk, lay around all day, commit petty crime, steal your women and birth hordes of Catholic children who in turn would lay around, drink and commit petty crime... The only deterrent to this madness being the local cop and his murder stick. See "Paddy Wagon" and "St. Patrick's Day in the U.S."
Alright Seamus... Are you going to come with us willingly or do the five of us need to pull our Paddy whackers?

A policeman's truncheon or baton. Arose from the fact that the Irish were generally on the wrong side on the law in the New World and as such were often on the wrong end of the paddy whacker.
