Question: I'm at a party. What's one word that is almost guaranteed to be misspelled?
Answer: I can think of several. "Cemetery." "Minuscule." But I think "sacrilegious" will get 'em every time.
"Sacrilegious": Does not contain the word "religious." Again, I use Harry Shefter's Six Minutes a Day to Perfect Spelling: "You RILE me with your sacRILEgious ideas."
Rating of Distraction: (*). I don't think too many people will even notice that the word is misspelled. And even fewer will ever use the word.
