Slippery ninja

The sexual act of masturbating onto a floor, leaving a sticky or slippery mess (depending on floor surface). An action intended to cause discomfort and annoyance to a female partner in the hope that she treads in the newly applied man-porridge.

*guy applies slippery ninja technique, girl walks into room* *squelch*
Girl: Oh my god that's disgusting! Why would you do that on the floor?!
Guy: I am slippery ninja, and as an owner of ovaries, you are the victim of my mischievous ninja deeds!

ninja-wanged

To surprise a ninja and get smacked by his spring-loaded erect penis as a result (or wang). In everyday usage, a term used to describe the result of colliding with a ninja or someone of ninja-esque qualities, resulting in disorientation and humiliation.

The ability to ninja-wang or to cause ninja-wangification or to possess a ninja-wang is reported to be an ancillary reason for a ninja's inherent stealth.

"Ninjas don't just walk slow to not be heard ..." -- John S.

Quote from a waking gaurdsmen:
"I didn't see him coming. I just walked around the corner, and the guy ninja-wanged me."

Quote from a Master:
"Nevermind the pebble. To truly be a master, you must possess the ability of the Ninja-Wang."

keyboard ninja

Someone who enjoys or needs to use the keyboard instead of the mouse to accomplish tasks in a computer environment. Knows a lot of keyboard shortcuts in one or many softwares. Usually is proud of knowing so and exhibits a feeling of slight superiority over those who use the mouse for everything.

Bill: Why don't you just press Shift-Space to roll the page up in Firefox? It is sooo much faster. If you keep using the mouse for everything you will never be a keyboard ninja.

Bob: Yeah, I know... ...L053R...
