Jacks
Heard in Kilkenny, Meath, Galway, Dublin and Limerick
The toilet or W.C. Comes from Shakespeare's King Lear (II ii 74-6),
I shall tread this unbolted villain into mortar, and daub the wall of a jakes with him.
I shall trample this unprincipled scoundrel into mortar and plaster the lavatory walls with his remains.
