A person who does everything in their power to creep on and eventually force you or a friend unwillingly into a non consensual relationship.
"I've been talking to Lauren a lot...and I think I just want to be friends...she seems to have other things in mind. I feel like I'm going to be walking in some dark alley and she will leap out of the shadows, forcing me into a meaningless relationship. Such a Relapist.
