Anonymous

When someone does something but doesn't want to be identified, for example a poem or a charitable donation.

Example:

I have lots of promiscous sex with someone other than my wife. -Anonymous

Notice, the person who penned this wishes to remain anonymous, that is, he is wishing to not be identified.

Let's take a look what would happen if the person identified himself.

I have lots of promiscous sex with someone other than my wife. -Ted Haggard

If Ted Haggard announces this to the world, he will lose his job as leader of the megachurch.

Ultimately, Ted Haggard bought meth and had gay sex with a meth dealer, and so his actions came to light. Out from the shawdows of anonymous.

Of course, here is another example, to end on a good note.

I didn't vote for George Bush in 2004. -Anonymous
