lone ninja 

The most badass superhero of all. Not just a normal ninja, this supremely superior savior has more skills than ever imagined. Not only is she ingeniously smart, but her cunning and grace can strike fear into the heart of even the worst of criminals. She is a advocate for good and the slayer of evil. She has one weakness, however, a flaw left in her evolutionary code: British Accents.

Guy One: Dude, I think I had a date with the Lone Ninja last night.
Guy Two: No way, man, I heard she foiled a roberey attempt at the Louvre last night.
Guy One: I dunno, dude. All i know is that this girl was smart, sexy, and intimidating.

Butt Ninja 

An incredibly pungent fart that occurs without warning.

I was in the middle kissing her when this BUTT NINJA comes out of nowhere and kills the mood! I was so embarrassed.

Ninja 

verb. To bail on a group of friends without any warning, only to return many hours later.

One may do this as a premeditated act to see another group of people, or as an unintentional byproduct of being drunkenly inconsiderate to your crew.

Dude, Brian ninja-ed us last night. We were walking to the party and he bailed to hook up with that skank.
