A term coined by Michael Stevens of Vsauce, Boil-o is an invisible, undetectable, unverifiable/unfalsifiable substance that appears whenever things begin to boil. While, yes, the phenomenon of boiling is perfectly explained without Boil-o, Boil-o is still there.
Boil-o is used as an example of redundancy. If a phenomena is perfectly explained without something, why include the something?

O. Z. stands for being overzealous, a brain disorder. Those afflicted do not know when to stop - planning a party down to the most minute detail, decorating a room or giving an endless stream of gifts on Christmas when a few would more than suffice. Frequently mis-diagnosed in children as industriousness or generosity, by adulthood it's incurable.
"I'll just tidy up", she said, heading for the kitchen, "a few minutes." Hours later she emerged, having rewashed the clean dishes, glasses and cutlery, scrubbed the floor, wiped, re-wiped and sterilized the counters, thrown out loads of perfectly good food to neaten the fridge and arranged their Urban Dictionary mugs in alphabetical order, her O. Z. out of control.
