ninja sex 

Contrary to popular belief, ninja sex does not have to be silent. It can include plenty of grunting, yelping, ass slapping, rapid bed squeaks, and dirty talk. Only the loudest screams of pleasure are discouraged, but are allowed if the place chosen to hook up is soundproof. For example, a bomb shelter.

To cover for noisy ninja sex, a covering sound is most common, although other techniques are also used (see above). All that is required for sexuals to qualify as ninja sex is that the sexuals are undetected by others not involved in the act.

Sontia tuned the radio in her boy's room to Radio Disney when she put him to bed, and turned it up a little once he was asleep, to provide cover for ninja sex with Tony.

Ninja Movie 

Ninja Movie n. Arguably the only kind of movie that matters. Particular high points include the films produced by Joseph Lai's IFD Film Arts in the mid-1980s.

"Yo dawg, grab that bag o' chips and a couple Colt 45s. We gonna watch a NINJA MOVIE."

Ninja Butler 

The Ninja Butler is a great and mysterious being... always using his power for good. He moves undetected in your home doing good deeds and bringing joy to all. His most common good deeds are bringing cups of tea, flipping the mattress and putting clean sheets on, and cleaning the kitchen sink.

His kindness knows no boundaries... his expertise knows no equal.

He's currently thought to live in northern England.

She looked down and saw a hot cup of tea that seemed to have appeared out of nowhere... the Ninja Butler strikes again.

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."
