The unholy union between a pirate and a ninja. Pirates and ninjas are widely known to be mortal enemies and are locked in eternal oppisition to each other.

Pirate-ninjas rarely exist in nature because they have extremely short half-lives; upon their creation they rapidly decay in a violent burst of short-wave radiation, heat, shurikens, and parrot feathers.
Pirates vs. ninjas - that ages-old question. Who would win?

The pirate-ninjas, of course!

Pirate-Ninjas are basicly Ninjas that are as smooth-talking or disguistingly rude as a pirate, and can also perform all ninjary whilst being fucked up like a pirate.

Weed and Liqour are the standard intoxicants required for ninja-piracy, although any upper, downer, stimulant, depressant, dissociative, or psychedelic can be used.

There are three Master Pirate-Ninjas:
Jay the Liar
RizN the Trickster
and Nic The Guy Who Is Quiet, Short, and Incredibly Sneaky

from there, the hierarchy goes:
Pirate-Ninja Advocates (pirate-ninja trainees)
and Morons (everyone else)
whoa, that guy just smoked 5 blunts, ate a gram of shrooms, then kicked atleast 9 or 37 people in the face, got laid real quickly, then dissapeared into the night. Damn he's a Badass Pirate-Ninja!

Something that can never possibly exist due to the deep-rooted feud between ninjas and pirates. And also because ninjas and pirates are so played out already that if someone were to create a pirate ninja, it would be some kind of horrible clichéd supermonster that would not only knock you down with its peg-leg but would also give you a roundhouse kick to the face if you crossed its path.
Poor Johnny didn't even have a chance to defend himself when he accidentally stumbled upon a pirate ninja. But luckily since pirate ninjas can't exist, Johnny was thrown into an alternate parallel universe before the ninja pirate was able to attack.

A ninja who has inherited some of the qualities of pirates, a typical example being their boldness (as ninjas are typically known for being stealthy at all times).
