• noun misfortune, curse, frustration. An expression which is used by schoolchildren as an exclamation, sometimes of defiance, more usually in an attempt to put off or jinx an opponent in sports or games. Mockers probably derives via the Yiddish makeh, from Hebrew makah, meaning ‘plague’ or ‘wound’, reinforced by the English words ‘mock’ and ‘muck (up)’. In adult usage the word normally appears in the phrase put the mockers on, meaning to ruin, thwart or jinx.
