Having sex as quietly as possible because there are people who could possibly hear you if you went at it the usual way.
My parents are staying in the guest bedroom next to ours so tonight we will have to have Ninja Booty.

A Ninja-Lunch is when your co-workers start talking about where to go for lunch, and while you give some token input, like, "The pub" or "The donair place on the hill", you really have no intention of going to lunch with the boys. You've already secretly planned lunch with a redhead, and while the boys' backs are turned, you vanish like a ninja to meet your REAL lunch date.
Dave: Where should we go today?
George: The Old Admiral?
Brian: Yeah....uh....yeah...
Yoon: How about Burgers?
Joe: Alright guys, time to go!!
Mike: Wait, where'd Brian go?
Yoon: He must have gone on a ninja lunch again.

when you pretend to be hard at work to get your mom off your back about homework, but you're really watching tv shows on hulu.
I was ninja studying last night. Learned everything off of bones and house. Think I'm ready for that biology test now!

A person who occupies a bathroom stall and refuses to make any BM noises until the entire bathroom has been vacated. Occasionally, a bathroom ninja will even go so far as to stand on the toilet seat to avoid detection by other bathroom-goers.
Jacob hid in the shadows cast by the stall walls like a bathroom ninja until the final shitter had left the restroom.

In RPGs and some MMORPgs, is another word for a character that can be in the forefront of the battle and survive the outcome due to sheer evasiveness rather than high armor and health. An example would be the assassin from the pseudo-MMORPG game "Guild Wars", especially in PvP mode.

Societal ninja (noun): an issue that caused great discourse in society. The issue was once at the very forefront of mainstream media’s attention, causing fierce debate and social divide along community lines; racial, religious, political, ethnic, gender and/or age. The issue is often deeply rooted in history and culture. Suddenly, the issue is gone without a trace from mainstream media; the key is there must be no resolution or majority acceptable action reached. The issue falls from the forefront of media often because another story breaks, acting as a ninja’s smoke bomb, and media never returns to the issue until it reappears as a result of the offenders actions-no more CNN or FOX headlines.
Example:
Malcom: Whatever happened to the two guys who dressed up in blackface in Virginia? Who was it—the govenor and attorney general and are democrats too?
Martin: That’s a good question, Malcom, I haven’t heard anything about that situation lately. It was on CNN and Fox non-stop for weeks and now it just disappeared without a trace. I guess they resigned. I really thought we had overcome.
Malcom: As I always say, I’m for justice no matter who it’s for or against and societal Ninjas such as these prevent communities from ever realizing justice and sustainable positive change. These soNinjas raise their ugly heads for a moment and then hide in the dim unknown giving people the false impression that it’s resolved, but it’s not. No justice no peace as the young folk say! I highly doubt if those Kats resigned.
Example:
Those dudes committed a federal crime and never went to trial and after one day of headline reporting it’s gone-that is soNinja! I think they likely paid off the judge because I haven’t heard about this in ages.
