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.

The one person you always try to,avoid at the bar but he somehow seems to show up out of nowhere and spews his drunk stupidity at you.
My girlfriend and I were having a great time at the bar last night and out of nowhere Pat appears , completely drunk , talking about his latest female conquest. He is such a fucking Alcoholic Ninja!

A person who lacks the common sense to avoid antagonizing ninjas. A social klutz who does not know how to behave in public. Missing hands or fingers is a sure sign, but not required.
I can't believe that you just ate my BK mini burger off my plate, you are such a ninja petter!
You: Let's wait for the light to turn before we cross.
Me: You are such a ninja petter, there's no traffic.

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.

Usually played on guitar, but just the same on piano, this is a series of notes that requires the player to stretch their hands out as far as humanly possible.
