ninja noise

Ninja noise is the electrically induced noise as a result of a ninja uncertainty quantum probability state of a room. Lighted rooms tend to have less ninjas than a dark room.

Ninja noise is an electrically induced noise due to the statistical presence of ninjas.

A lighted living room of around 30m^2 has an average estimated amount of 20 ninja's. Dark rooms approach quantum levels that make it impossible to estimate the amount of ninja's mathematically. Because of the statistical backgrounds, one can never tell if ninjas are there. Only the probability due to the quantum ninja wave function. According to the principle of Heisenberg, the position of the ninja and the speed can never be determined at the same time.

cyber ninja

A term relating to hackers and scammers who are getting better at covering their tracks or fooling the public into falling for their tricks.

If you think the most common cyber scam still involves deposed Nigerian royalty eliciting your help to extract fortunes from African banks, your time machine has stalled. Cyber ninjas have become far more creative, sophisticated and inscrutable.
