Ninja Chuck

Bill drank too much last night. He ended up ninja chucking his beer all over the bathroom.

I just ninja chucked so hard I punched the wall.

ninja chirpse

Chirpse so subtle, but effective, that the other person doesn't realise until it's too late

Guy 1: Dude I totally scored with that girl last night!
Guy 2: Really? She didn't seem that into you...
Guy 1: It was a classic ninja chirpse

Ninja Typo 

A Ninja Typo is a punctuation or grammatical error that does not reveal itself to the author (no matter how hard the author looks for it) until it is too late (i.e. after it has been published in a way that cannot be retracted).

Example : Dang! I proofread this email 3 times and I STILL managed to leave the "l" out of "turtle". That Ninja Typo just killed my chances of getting re-elected.

rafters ninja 

Somebody who always seems to know where everybody is at all times, even when huge amounts of effort have been taken to ditch them.
Originates from the way in which they travel mostly through the rafters, so as to stay out of everyone's awareness like a ninja

Person 1) Wow... I can't believe it, we managed to ditch Barfield. Now to spend some quality time with the amigos without jokes being undermined etc.
Barfield) *sprints along rafters like a Shinobi, darting from the shadows with unprecedented stealth* Hey guys, what are you all doing in town? You told me you all had the plague... You weren't tryin to ditch me, were you?
Person 2) Jesus, you're such a fuckin' rafters ninja
