Hoosedinger:

- the feeling one gets when they are desperate to know the meaning of a word but their brain somehow impedes them to remember, therefore, causing fustration and "upsetedness"

The history of Hoosedinger:
One day, Mr. Fitz went up to the board and said:
"I want you to draw a graph on a hoosedinger travelling along a ramp"
"What's a hoosedinger sir?" the student asked.
Sadly, nobody understood the explanation, and from that day on, hoosedinger got it's meaning.
