Ninja Mission

When you do something you know you're not supposed to do (whether it's good or not so good) or when you do something that other people (like your parents) don't want you to do.

Well...sneaking out to Caid's party at 11 p.m. was a real ninja mission.

Ninja whinger

Someone that complains by stealth in order to undermine their victims.
A person that uses something you've told them in confidence to get at you behind your back.
Someone that deliberately puts shit on you for personal gain.

Heads up man, that mofo is a ninja whinger - don't tell him shit.

ninja master

person worthy of leading a team of true ninjas (people that quietly and skillfully gets things done without drama).

Brian's a superstar at this company because he is a ninja master, and you have to be able to walk through walls to be a part of his team.

boo ninja

A Boo Ninja is a man who consistently scores women which are obviously way out of his league. Most often the Boo Ninja is spotted in bars working his magic. In this setting the Boo Ninja will look much like a scout master holding court with his young charges gathered around a camp fire. But the Boo Ninja is no scout master and his charges are not suburbanites but rather really hot young women and with each word the Boo Ninja speaks his audience will either laugh or compliment him on his wisdom as each competes to be his paramour {fuck} for the evening.

"Look at that bald fat fucking old Boo Ninja... he is old enough to be their fucking grandfather, he had the damn valet park his Yugo and yet look at all of that fabulous {highly fuckable} , boo {pussy} hanging on his every word like he is some fucking mullah {Islamic preacher} issuing a fatwa {religious decree}.
