unctual
the line protruding from the bottom right of a capital 'Q'
In my 9th grade math class, I had this teacher who went to high school with this guy who was really smart. He would put vocabulary words on our math tests and one day we were all bored in class, so this kid asked the teacher "what is the thing on a Q called?" The math teacher told him to go see his friend and ask him. The kid came back and said "He does know it. It is an 'unctual'."
