Eheu

(Latin): An exclamation of sorrow or anger; Oh no!, Oh dear!

An exclamation of calamity, misfortune or bad karma. Derives from Latin exclamation ("eheu" literally translates as "Bummer!").

Likely to be the only word a student remembered from Latin class, at least in the days when students actually learned Latin rather than Media Studies and Modern Dance.

Popularised in Geoffrey Willans and Ronald Searle's classic "How to Be Topp":

(The headmaster and all lat. masters who watch roar with larffter)
RADIX: Eheu!
(More larffter they are in stiches)
CORTICUS: Eheu!
RADIX: Eheu!
(The curtain falls as the masters rolle helplessly in the aisles.)"
