a kilowatt-hour per martian day

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.

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.

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.

Term used for an extremely popular and cool person. Also can be used before the words Super and Saiyan to say more than one uber awesome dude. One word.

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).

The most fricken amazing thing ever created.
