DOLLARS is a colorless Color Gang from the anime "Durarara!!" Here is the History from the Durarara!! Wiki:

"Dollars is an online colorless gang, whose name is derived from "dara dara" (meaning "no use" or "not doing anything"). Anyone could join but by invitation. The members would be given a password used to enter the main site. They'd be known as "daras", or Dollars."

Although the gang appears to be named after American currency, the name actually derived from the Japanese term "dalla dalla," roughly translating to "useless" and "not doing anything." This is because the gang was created with no purpose in mind, the gang rarely ever involve themselves in any group activities, and its members are "colorless" and "invisible," only identifying themselves as Dollars when specifically asked.

DOLLARS apparently connected with many people who watched Durarara!!, because there are several sites dedicated to recreating Dollars.

To those not familiar with Durarara!!, the point of this post is not exactly seen. It's notable to some people, even if it's not to you.
