The Washington Post's "Style Invitational" asked readers to take any word from the dictionary, alter it by adding, subtracting or changing one letter, and supply a new definition. Here are some recent winners (1998): Doltergeist: a spirit that decides to haunt someplace stupid, such as your septic tank. Sarchasm: the gulf between the author of sarcastic wit and the recipient who doesn't get it. Contratemps: the resentment permanent workers feel toward the fill-in workers. Reintarnation: coming back to life as a hillbilly. Hipatitis: terminal coolness. Dopeler effect: the tendency of stupid ideas to seem smarter when they come at you rapidly. Foreploy: any misrepresentation about yourself for the purpose of obtaining sex. Intaxication: euphoria at getting a refund from the IRS, which lasts until you realize it was your money to start with.
