Schdenfraude is a negative, unproductive emotion. For example, if a hated ex partner breaks up with the girl he replaced you with, the feeling of delight that is washed over you is called schdenfraude.
"Ha! Kynan broke off the engagement with Elaine! She so heartbroken. Schdenfraude never felt so good!"
