[Hollow Point]
It's an idiot term that has been taken WAY out of context in modern day usage.

Dion Fortune wrote of psychic parasitism in relation to vampirism as early as 1930 (considering it a combination of psychic and psychological pathology) in "Psychic Self-Defense". [4] The term "psychic vampire" first gained attention in the 1960s with the publication of Anton LaVey's Satanic Bible. LaVey, who stated he had coined the term,[5] used it to mean a paranormal entity within such a person allowing the psychic draining of energy from other people. Adam Parfrey likewise attributed the term to LaVey in an introduction to The Devil's Notebook
The theme of the psychic vampire has been a focus within modern vampire subculture. The way that the subculture has manipulated the image of the psychic vampire has been investigated by researchers such as Mark Benecke[6] and A. Asbjorn Jon.[7] Jon has noted that, like the traditional psychic vampires, those of vampire subculture believe that they 'prey upon life-force or 'pranic' energy'.[8]

nice little reference job. Another note: draining the life force from another person wasn't always seen as an act of vampirism. The idea of being able to came long before lavey.
