Ninja Defuse 

The stealth and silent act of masturbating with other people in the room. A properly executed Ninja Defuse leaves all other people in the room unknowing of your deed. Most common in college dormitories and sexless relationships.

Guy 1: Dude i'm really horny, i need to go rub one out but my roommate is always sitting around playing Call of Duty.
Guy 2: Bro you need to try a Ninja Defuse.
Guy 1: WTF is that?
Guy 2: Just throw your covers over yourself in bed, and masturbate while he isn't paying attention, but keep quiet or you'll get caught!
Guy 1: Oh damn son! You're a genius!

transgender ninja 

A transgender ninja is someone who perfectly imitates the opposite sex to fool or fully become one with the sex. Some transgender ninjas cover it up so well you wouldn’t be able to even no they were trans. Most transgender ninjas hide their birth sex from their partners allowing them to believe that that is who they were.
