As a kid I used to read the dictionary hoping to become a spelling bee champion. And then I was in one and purposely misspelled a word when I got nervous. I thought it would be better to intentionally misspell rather than actually misspell, somehow that would have been less embarrassing? A 5th grader's train of thought is my only defense.
So some of my favorites are: ameliorate, shenanigan, meander, hippopotamus, waft, ineffable, foliage, facetious, drift, fetching, dashing and awesomesauce.
