The act of releasing a totally disgusting and gross fart without a sound. Hence the term, silent but deadly!
While watching TV, Carol cut a ninja fart that grossed out her boyfriend. Since there was no sound, she was able to blame the dog! Her boyfriend almost puked and the dog ran away!

I love to release my ninja farts when I am standing on the diving board before a dive. It really fucks up the next competitor.
I also love to release my ninja farts while getting my salad tossed by a male prostitute.

The act of putting your hand over your butt, farting into your hand, closing your and entrapping the fart, and then throwing it into some one elses face like a ninja throws a star.
