My Favorite Words

I was bored, unsure what to write and my head is too full of Harry Potter for me to think. So I just thought I'd share my three favorite words.

troglodyte- a)a member of any of various peoples (as in antiquity) who lived or were reputed to live chiefly in caves or b) a person characterized by reclusive habits or outmoded or reactionary attitudes

triskaidekaphobia-fear of the number 13

facetious-joking or jesting often inappropriately or b) meant to be humorous or funny : not serious

I like all of them because of the way they just role off of your tounge. What are your favorite words? Why?
