chanchi is what you get when you mix chonga and raunchy. its an adjective..it is used to describe mostly latin young adults that like to shop in stores such as Rave and 579 or wear SouthPole and Fubu. They are known to say 'meng' and mean it.
That party sucked. There was a bunch of chanchi girls doing the crybaby like it was still 94'.
Those rhinestone playboy shorts are chanchi as hell, remove them immediately.
