Someone appointed from another institution by a university to
question every
little, trivial detail of an assessment or graded
paper in order to justify their own hefty stipend, make lecturers' lives annoyingly miserable (thus reminding them they are still only employees) and to feign the appearance of academic quality.
Elvira: Leo the external examiner has returned your examination for review because some of the questions require commas to be added. Make sure you do this before you leave the office at 2.30pm today.
Chuck: If all Leo has to do for his
money is correct my
grammar, then I'd be grateful if you'd ask him to stick that examination
paper up his fat arse.
