adj. used in reference to something that was/is particularly and especially janky, rude, uncalled for, irritating, ridiculous, inappropriate, shitty, or crappy. The term is normally used in an extremely unserious manner (though janky can hardly be considered more so), so be sure to follow its use with large amounts of laughter.
Instead of saying, "That shit was hellajanky," you could say, "Ooh, that shit was jankalicious!"
or "That bitch was jankalicious. Who does she think she is?"
