What is Nypa?
1.
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.
"HAY GUISE, this dude fucked my girlfriend...here's his myspace"
"NYPA faggot"
