Each year, the Washington Post hosts the "Mensa Invitational" in which readers are asked to take any REAL word from the dictionary, alter it by adding, subtracting, or changing JUST ONE letter, and supply a new definition for it.
You must look carefully at these as they are VERY close to words you already know.
Some of this years winners are:
Cashtration (n.): The act of buying a house, which renders the subject financially impotent for an indefinite period of time.
Intaxication (n.): Euphoria at getting a tax refund, which lasts until you realize it was your money to start with.
Reintarnation (n.): Coming back to life as a hillbilly.
Bozone (n.): The substance surrounding stupid people that stops bright ideas from penetrating. The bozone layer, unfortunately, shows little sign of breaking down in the near future.
Giraffiti (n.): Vandalism spray-painted very, very high.
Sarchasm (n.): The gulf between the author of sarcastic wit and the person who doesn't get it.
Inoculatte: To take coffee intravenously when you are running late.
Hipatitis: Terminal coolness.
Osteopornosis: A degenerate disease. (This one got extra credit.)
Decafalon (n.): The grueling event of getting through the day consuming only things that are good for you.
Glibido: All talk and no action.
Dopeler effect: The tendency of stupid ideas to seem smarter when they come at you rapidly.
Arachnoleptic fit (n.): The frantic dance performed just after you've accidentally walked through a spider web.
Beelzebug (n.): Satan in the form of a mosquito, that gets into your bedroom at three in the morning and cannot be cast out.
Caterpallor (n.): The color you turn after finding half a worm in the fruit you're eating.
