When, at a party or dance, a random male comes up and dances very close to, or grinds on you. This is used more when the person that received the random dance is also a man.
Male A: Oh shit dude, I just got manjangled!
Male B: Yeah, I saw that. You get his number?
Verb: To get fucked up or manipulated, mentally or physically, in any way, shape, or fashion... no matter what it is.
