1.) Literally, work that is done at home. Usually applies to schoolwork. Homework is unnecessary as it is given to students who have already spent the majority of the day at school.
2.) Something that gets
crueler with every grade. While the first graders chug away on their addition worksheets, they are blissfully unaware that they will soon enough be doing laborous tasks such as
AP World History homework, Geometry 2 homework,
English Honors homework, and even Gym homework on a nightly basis.
3.) Assignments that are wickedly easy to procrastinate on whenever there is a preferable activity at hand, such as YouTube, Xbox, or being impaled by a molten iron spike.
4.) What you are probably supposed to be doing at this very moment, seeing as you looked up "homework" on urbandictionary. I would go so far as to say you have a very LARGE amount of it.
