Giraffiti: What does it mean? Words & Definitions

The Washington Post runs a contest where they ask readers to take any word from the dictionary, alter it by adding, subtracting, or changing of one letter, and supply a new definition. Here are some choice examples (thanks to Krystiina):

1. Cashtration (n.): The act of buying a house, which renders the subject financially impotent for an indefinite period.

2. Intaxication: Euphoria at getting a tax refund, which lasts until you realize it was your money to start with.

3. Reintarnation: Coming back to life as a hillbilly.

4. Foreploy: Any misrepresentation about yourself for the purpose of getting laid.

5. Giraffiti: Vandalism spray-painted very, very high.

6. Sarchasm: The gulf between the author of sarcastic wit and the person who doesn't get it.

7. Inoculatte: To take coffee intravenously when you are running late.

8. Uno: What you insert, you know, while, you know, you are deciding what you will say next, you know.

9. Hipatitis: Terminal coolness.

10. Karmageddon: It's like, when everybody is, like, sending off all these really bad vibes, right? And then, like, the Earth explodes and it's like, a serious bummer.

What can you come up with?
