Interesting Word - LOL

Most people now know that LOL means “laugh out loud”, but did you know that it used to mean something completely different?

(It used to mean “little old lady”: The 1960 book, Only In San Francisco, written by San Francisco Chronicle columnist Herb Caen. It contains the passage: ‘A traffic officer bellowed at a LOL who didn’t seem to know which way to turn her car. Use your noodle, lady, use your noodle!’

20 years later that the meaning of LOL changed and it became so widespread that it was added to the Oxford English Dictionary two years ago.)
