Ninja

A silent-but-deadly fart normally released to assassinate unsuspecting bystanders in small cars, phone booths, and long elevator rides. These ninjas are known to have not only render average humans unconscious, but clear funeral homes, meeting space, classrooms, and other places where people would be caught with their guard down and nostrils open.

I almost died in at the office today when headed to the 47th floor in the elevator some jerk blew-ass released a ninja and everybody suffered from oxygen deprivation.

Ninja

The un-official term used to describe an internet forum member who possesses moderator powers, but no title. Ninjas are swift, silent and deadly. Ninjas edit and lock threads without warning often killing threads with a single blow and then quickly vanishing. Only the most trusted members become Ninjas. See Ninja Edit
