look up any word, like blumpkin:
A lust-bunny or lustbunny is a term used to define someone you lust after. You may or may not know this person but they do visit you in vivid sexual fantasies and/or erotic dreams. One can have as many lust-bunnies as one wants!
I am only friendly with Josh since his girl-friend is my lustbunny.
