The ninja 

While the woman is sleeping you come in dressed in black with a black headband on as if a ninja. making sure the woman still sleeps you tie up the woman to the bedposts doggy stile and gag her with your black headband. Then taking a good 15 steps back, you run do a flip over the headboard and perform the roundhouse hump (a move which was created by chuck norris of course) and the success of this move depends on the landing and being able to stick the move.

the ninja-ghost-sex move 

when someone goes into a dark room or area with intentions to have sex with someone (or otherwise cannot see their intended partner), then, after the sexual encounter, finds out they had sex with someone else without knowing it.

Melanie went into the room and thought she had sex with Chris. However, she really had sex with Lambert. Wow, Lambert did the ninja-ghost-sex move on her.
