I love the occasional made-up word. When someone says "flusterated" it makes my day. Or when I hear "irregardless" I smile and think of my dad (who hated made-up words).
But I heard the best one ever recently: Parannoys--as in "it parannoys me when I think I'm being followed by a monster." Parannoys: a clever combination of "paranoid" and "annoys." Beautiful. Or, as the kids would say, "that is prettiful."
