ninjafart 

Flatulence occurring in the presence of another or others that requires "hands-free" manipulation of the anal sphincter to expel the gas in silent undetectable manner.

I was having fun driving you guys to the ice fishing expedition until someone released a ninjafart. Too bad it was SBD, or it may have gone completely unnoticed.

ninja fart

A silent, yet super stinky fart.

I love to release my Ninja Farts just before exiting the elevator.

Ninjatard 

Retarded kids whom consider themselves intelligent because of their Counter Blox inventory. You can usually find them lurking in the Ninja's Trade server on discord, prowling the text channels in search of unsuspecting prey to shark. They tend to be vile and vocal creatures, with their one liners being, "WhAt AbOuT dEmAnD" and "CaStLeRs AnD aImEr AbUsE tOo MuCh".

Enzo tried to frame Aimer for alt trading with fabricated DMs. Kinda a fucking Ninjatard.
