BUBBLEGUM

Used to negatively descibe trendy pop items (songs, clothes, etc.) that are just too happy, shallow, and myopic. Something Old Navy or Gap might sell--lots of plastic and bright colors. Also describes someone who closely follows these trends, superficial and narrow-minded. Example: I liked the Matchbox20 song, but it was bubblegum. That bright lime green tech vest is so bubblegum, I want to puke.
