look up any word, like bukkake:
a person who frequently writes negative statuses with no context on a social networking site and basically makes a fool of themselves without giving anyone any real insight. (See also: Vaguebooking)
Person A: "Hey, Todd wrote some weird status saying he's sick of his life. What's that about?"

Person B: "I don't know, but he's being a real Vague Vagina right now."
