QotD: Good Catch!

Do you have a particular "catch phrase" for which you are known?

Yeah, unfortunately lately my husband had been catching me using "misunderestimated" in sentences. Embarrassing.
I half heartedly try to justify the need for such a word. Because sometimes you don't just under-estimate you actually mis-under-estimate. Like for example "He misunderestimated her jean size." A word totally appropriate if you both mistakenly estimated and underestimated. Right?

This reminds me of the severe lack of brain function I've been experiencing lately. I was watching my son play with his new Elmo Tub Sub toys in the bath tonight. I wondered why the sub wasn't floating. I thought to myself, "The box said, 'Toys Float' What the...?" I later had an "aha" moment when I realized that sub marine meant under water. I swear I'm college educated.
