An adjective to describe something or something that is both cheesy and tacky. Initially born at a window shopping trip in downtown Boulder, CO (where the fashion is questionable to say the least). I had to react to a hideous outfit and couldn't decide whether it was cheesy or tacky, and "chacky" just spilled from my lips.
Mavis, look at that girl's outfit. It's totally chacky.
Josh, breaking up with a girl over text is chacky.
