Yes, it's a word...it just so happens to be the word that my Father-in-law taught my son over their Easter weekend visit! Ironically, it's definition is "the practice of a person who likes to use big words in excess." LOL...that's my boy!
Oh, and YES, if you notice that he's never wearing a shirt...he won't keep it on! I do dress him, but he always says "I got hot and 'svetty' Mom" and off it comes. *sigh* My only consolation is that between the two of them, they usually have on a complete outfit. :) Such is life in a household of men...of all ages!
