grave-dancer(redirected from a gravedancer)
One who delights in or benefits from someone else's death or misfortune. I'm sure Laura's thrilled that my venture failed—I know she's secretly a grave-dancer.
n. someone who profits from or takes advantage of someone else’s misfortune. (From dance on someone’s grave, seemingly in celebration of someone else’s misfortune.) I don’t want to seem like a grave-dancer, but his defeat places me in line for a promotion.
