Guns are Ninja. Sex is Ninja. Killing terrorists is Ninja. Killing in general is Ninja. Bombs are Ninja. Beating someone is Ninja. Stealing massive quantities of money is Ninja. Eating meat is Ninja.

Get the Ninjamug. by Gregory cit May 13, 2005
Get the ninjamug. A mythical being who exists to give people wedgies. As with the Tooth Fairy, Santa Claus and the Easter Bunny, the Ass Ninja visits all the little boys and girls in order to bunch their underwear at the worst possible times.
"Dude I totally just got visited by the Ass Ninja! Cover me while I pick my underwear out of my butt."

Get the ass ninjamug. The most elite, efficient class of stealth warcraft. Their existance is unknown to all but a select few. To become a sniper ninja, you must be able to shoot a mongolian's left testicle from 500feet awat while at the peak of an orgasm.
Person 1: "Holy FUCK dude, why did you just drop kick that baby!!??!?!"
Sniperninja: "Its O.K, I'm a sniper ninja."
Sniperninja: "Its O.K, I'm a sniper ninja."

Did you see the Cruiser in that dumb movie? He was even smaller than the Japs. Looked like a Goddamn leprechaun ninja!

Get the Leprechaun Ninjamug. Like a fucking ninja is when you escape from a place or thing or situation or person without being detected.
"And while she turned around to see where the noise came from, I jumped up and escaped through the vents. Like a fucking ninja
