The complete opposite of invisibait. Instead of somone who lurks and waits for people to log on to their chat program so they can annoy them, Invisibitches lurk on chat programs refusing to talk to anyone who doesn't message them first. They usually sit around playing video games and lurk on their chat program waiting for friends to ask them if they are there (usually knowing that they are on)
