kitsch
As an art movement, lifestyle, or literature and film genre, kitsch is pleasingly distasteful. It's melodramatic, overdone, gaudy and tacky or sentimental and folksy. It's so bad that it's cool. Your cat might attack it, but it's hot.
And, no, Martha Stewart and Jerry Springer are NOT bad enough to be kitsch. At all. Paris and Nicole though...
You're looking rather kitschy today, your grandma's neckace is hot.
I saw an awesome Andy Warhol knockoff at the galley yesterday, it was so kitsch. I couldn't get it though, I didn't have the cash. *sounds dissappointed*
