I love it when I come up with a word that just seems to fit the context, and then I start doubting myself and then I look up the word and it turns out I was right.

It's a much better feeling than not looking the word and then the word turns out to mean something else, like shedding feathers instead of thinking or something. I once did this in real life with the word "sleazy." I guess I thought it meant sexy but in a more refined and appropriate way than what Fergie was singing about in Fergalicious.
