ninja vodka 

any brand of vodka you can drink like water and then a few hours later it sneaks up on you like a ninja and knocks you out

We had the new Three Olives Watermelon Vodka last night. One moment I was up walking around...next thing I know it's tomorrow and I'm waking up on the couch. Either my tolerance is low or that's some ninja vodka.

ninja driving 

Ninja driving is the phenomenon that occurs when you kind of know where you are, and you kind of know where you are going, but you have no idea how to get there. Then, by harnessing what can only be called "the force," you end up at the predetermined destination.

Many people have experienced ninja driving without knowing its name. Others have been trained by ninja driving masters. The concept of ninja driving can be extended to include ninja walking, ninja biking, ninja scootering, and possibly ninja public transportationing.

Say you are downtown, and you need to get somewhere in the suburbs that you have never been before. You're going off the grid system, yikes! You only have an address -- no directions. You decide to ninja-drive there. While ninja driving, you use landmarks and a trained sense of intuition and end up where you want to be. You never call for directions, you don't use the internet, and you never consult a map. You arrive at your destination.

Person: "Did you get directions off the internet?"
You: "No, I ninja-drove here."

Ninja Dump 

A bowel movement that is stealthy, silent, and quick, but results in total destruction. The defecation community's equivalent of a Silent But Deadly fart.

Ron: "Dude, I Just took a Ninja Dump! Stay out of the bathroom!"
James: "But you were only gone for a minute, and I didn't even know you were in the bathroom!"
Ron: "Precisely!"

Ninja Booty 

Having sex as quietly as possible because there are people who could possibly hear you if you went at it the usual way.
