MUNDANE MYSTERIES: Why do ghosts say “boo”?

Halloween is 20 days away and between now and the 31st you will hear and see a lot of ghosts saying “BOO”. But why? And where did that come from?

The Oxford English Dictionary says that the term “boo” came from the Latin term boare and the Greek word boaein which mean “to cry aloud, roar, shout.” So when Halloween comes and you hear a ghost try to be scary and say “boo,” just remember that by definition they are saying “I’m yelling,” which is hilarious and very Casper like.
