look up any word, like sex:
 
1.
1. A sexual attraction towards ghosts, poltergeists, phantoms, and/or demons. Sometimes a parasexual may be attracted to aliens or Sasquatch.

2. Also getting freaky with ghosts.
Express your parasexuality by shagging a ghost.

Or when you can't stop thinking about that sexy ghost from "The Grudge."
