I had an aunt who reputedly went through an entire conversation with a new male acquaintance at a party, using the word "erotic" when she meant "erudite".
This probably wouldn't matter today, but 50 years ago.......

Georgiansilver, isn't "should of" a mispronunciation of "should've"?
I agree it's dreadful,when it's clearly "of", but I fear it's grammatically correct otherwise.
