The term for declaring something to be worthless trivia is floccinaucinihilipilification, often identified as the longest non-technical word in the English language. The word was coined by students at WHAT ELITE ENGLISH PUBLIC SCHOOL, the alma mater of 19 Prime Ministers, based on a list of verbs in their Latin grammar? (The school was founded by the king in question 3, coincidentally enough.)
