Excel Ninja

One who is adept in the exquisite art of Microsoft Excel. Frequently one with professional experience requiring extensive use of Excel (e.g., investment banking, financial analysis). Specifically the abilities to do things with Excel for which it was not intended (e.g., word processing) or create files quickly using arcane keyboard shortcuts are common traits of the Excel Ninja.

Chris: I want to fix this spreadsheet so that instead of having equations, the numbers are hard-coded.
David (with hesitation): Control + C, alt, e, s, v.
Chris: Truly your status as an Excel Ninja is beyond question.
David: Booyah!

Ninjago 

A LEGO TV-Show with 5 (really hot) ninja called Lloyd (the green and hottest one with his energy balls), Kai (the firehead), Zane (Let it go! Let it go! The cold never bothered him anway...), Jay (if he starts to talk: RUN!), Cole (the first time he's a human, then a ghost, now a human. Gosh, he's almost like Garmadon!) and Nya (she shows how to mix water with elictricity, don't even try to try!). They're saving Ninjago in six awesome seasons from assholes like the overlord, the nindroids, master Chen, the anacondrais, Morro and his ghost army, Sensei Yang or Nadhakan with his pirates. With an overprotecting uncle named Sensei Wu and many, many, MANY Love-Scenes you can't be bored anymore!

Besides, with 64 episodes, 2 pilot episodes and a 45 minute special, it's the longest LEGO TV-Show ever made! And it's not over yet!

"If Ninjago's new season comes out this year, I would be the happiest person on earth!"

"Hey, aren't you Lloyd from Ninjago? Oh my god, please give me an autograph!"

"Hey, Ninjago is on TV now! Do you want' to watch Ninjago with me?"

brain ninja 

A person with the ability to insert thoughts or ideas into another's head that does not cause immediate, but rather long term lingering mental anguish, usually having comedic value.

Walk up to someone. Look at them thoughtfully for a moment. Sing, "I've got a golden ticket." Walk away. BAM, you're a brain ninja.

ninja date 

When a person gets you to go on a date with them unknowingly. The person invites you to a group social event, but then is magically the only other person to show up to the outing and proceeds to treat you like a date.

Damn, I was forced into a ninja date! Josh asked me to go to the movies with him and some friends from high school, but then he told me in the car that nobody else was coming! He refused to let me buy my ticket and kept trying to put his arm around me the whole night!
