A person whose life is extremely oriented around grades and who would therefore do anything to get good grades. Someone who cares excessively about grades and therefore does not have a social life. Also known as a grade-grubber. In some cases, a teacher's ideal student. Usually a social outcast/misfit.
"Anu told me that she would even run around the school in a bathing suit on a winter's day for extra credit. Grade-whore!"
"Ugh, I know my teacher marked me wrong on this question. I'm going to go argue for my 1 point."
"Why? You got a 97% on that test, don't be such a grade-whore."
"He couldn't make the party because he was too busy studying for his Calculus test. Grade-whore."
An intensely large, overbearing, and excessive amount of something. This may be something dreaded, considering that the word 'hell' is embedded in the word itself. Similar to crapload, shitload, motherload, etc. A load from hell.
Oh man, I have a hellload of Spanish homework to do tonight...looks like I'm going to be pulling an all-nighter. T_T
This is a hellload of food, I knew I should've just gotten a happy-meal.
