Acronym for "Not Your Personal Army". An old phrase used by /b/tards to newfags who wish to cause a ruckus with raids and pranking. Essentially saying that Anonymous isn't a resource to use for your own personal vendettas.

(noun) A successful type of theft which results in an acceptable, impressive and rewarding payday for the protagonist.

Not Your Personal Army. Originated on the 4chan's /b/ as a response to any person that would try to exploit the /b/tards in order to achieve some sort of personal revenge (i.e. raid requests). Can be bent to fit a broad range of situations where an individual seeks help, but does so in an inapropriate place, tries to hide his real intent behind a stupid facade, or is simply too annoying and persistent to deserve better.
