Undeniably one of the sneakiest and scariest ASSassins of the world. Known for being able to PENETRATE the most secure facilities in the world with incredible ease with the sole intention of raping man ass. Butt ninjas have super human abilities allowing them to walk through walls, turn invisible, cling to ceilings, and run faster than light... translation: they will have sex with your butt no matter what.
Bro-1: "I was too afraid to shower at the empty gym last night. I kept thinking I saw a butt ninja out of the corner of my eye."
Bro-2: "That's a lie, a butt ninja would've never gotten spotted by a douche like you. Probably just a normal rapist."

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.

A supreme master of the alcoholic beverage so much so that it becomes a way of life.Someone as stealthy, quick and skillful as he could easily kill u in seconds but instead dedicates his life to getting u wasted.With his flawless recipes and extreme mastery of presentation his drinks may lead to a blissful state of enlightenment.By the time u come to the realization that your bartender may be a ninja bartender its too late.For you are plastered beyond comprehensible belief.
