Saint Glinglin
From Wikipedia, the free encyclopedia
Saint Glinglin is a fictional French saint. The name probably represents humorous onomatopoeia. The exact origin is unknown, but there are various fanciful theories. The expression dates back to the year 1897.
The French expression À la Saint Glinglin (on Saint Glinglin's Day) means "some day in the indefinite future, or quite likely never".
Similar concepts in other languages are the German Sankt Nimmerlein, the Portuguese São Nunca (Saint Never), the Dutch Sint Juttemis and the Latin expression ad calendas graecas ("on Greek Kalends"; used because the Greek calendar did not have calendae).
