a cute name for a catch-phrase that literally becomes a family maxim/motto worthy of being included on the family's coat-of-arms.
a small boy comes to his dad and asks: "what is it again, i can't remember, your famous cherry-phrase in Latin, that you use, when describing the origins of human ethnocentrism and xenophobia?
father: The cherry-phrase you are referring to is damno quod non intelligo
. Now what I was going to add, Alex, is that you have a goldfish's memory
. don't take offense, since this is an IMHO comment.
