Ninety-Niner

A person who moved out to San Francisco during the Internet gold rush at the turn of the 21st century, roughly in the year 1999.

It is a play on the term "Forty-Niners," which refers to people who moved out to San Francisco during the gold rush around the year 1849.

Yes, I did come to San Francisco in August of 1999 to work for pets.com, but I find the term "ninety-niner" offensive.
