In a poetry section of my AP English class, we read a poem about a guy who picked some apples. That's all that it was about, really! So our teacher asked us, what did it mean? One kid pipes up, "it symbolizes death!" The rest of the class had no idea what he was talking about, but the teacher agreed. So, we had an argument about it for the rest of the period. Then, one classmate remembered a story about someone who had used the fake word "insegrevious" in a college paper, and decided that we should make our own definition for it. So we gave it the above definition, and it became our class word. So, of course, I had to put it in my speech.
There are many forms to this word including, insegreviot (n.), insegreviator (n.), insegreviousness (n.), insegreviously (adv.), insegreviation (n.), and many more.
