a ninja move is when you or someone else does something behind your back or you do it behind theirs. this can be used in almost any tense. the reason behind this is well think about it ok. ninjas do shit and get away with it without being seen whether they are doing good or bad things to people.
1. i just pulled a ninja move on jon and fucked his girlfriend when he was in the room next to mine.
2 i just ninja'd that cop. he believed i was the guy in the pic on my fake drivers license.
3.did you just see me ninja that fucker that stole my weed earlier and he didnt think i knew who did it? he was knocked out cold and has no idea who blasted his punk ass in the dome.

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.
