One word I can think of that can yield very embarrassing results if mis-typed and 'corrected' by spell check is "DUCK". Because the program I believe, in part, suggests alternatives based on nearness of keyboard characters. For example, assuming you meant "i" instead of "o". So with the word "duck", there are 2 situations that can potentially get you in trouble. "i"/"o", and "d"/"f".

Spell Check and Auto Spell are not always friends.
