Mark Grunt

The types of people who get great marks in exams, but dont get full marks.
eg: 18/20, 47/50, 90/100
these people get these marks, and act like its the end of the world for them so that they get pity and attention, these are also the types of people to meaninglessly remind teachers about homework or tell the teacher to suspend a student due to a minor inconvenience

Frankie's such a Mark Grunt! He cried when he got a score of 95/100!
