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!

French Grunt

(Noun) The first partner readies a pot of hollandaise sauce; wearing a beret and a baguette, under one arm; all on an exercise bike, nude. The second partner then completely lubes up with half of the Hollandaise, being careful not to lower the temperature of the pot too much as this will ruin the consistency. Return to heat. Finally, with a running start and holding two live parrots; the second partner dives onto a prepared slip-and-slide, now aimed with the precision of a laser-guided missile, into the partners' awaiting orifice. The anal cavity is traditional, but records indicate that any orifice works.
The act ends with the first partner's lungs compressed by the force of the initiation of the act, creating the "Grunt" we're all familiar with, today.

Dude 1: "Did you hear; Stacy gave Deborah a French Grunt?"

Everyone in earshot: *Projectile vomiting sounds*
