A stalker is someone who says "You belong to me and I have your soul"...OR "Your mine and I won't let anyone have you." He also points out that he knows everything about you and questions on a daily basis "Did you fuck anyone?" He follows you around like he has no sense. He becomes
threatening when you ignore him or show no interest. He has his friends(errand boys) keep tabs on you...they report everything to your stalker. He acts like there was a relationship...when there was none. And he gets off on creeping you out or pissing you off...as long as you don't
ignore him. ANY attention ...even negative attention is a good thing to a stalker. BUT DO NOT IGNORE THEM...they can't stand that. They are normally possessive,obsessive and just plain delusional.

It seems to be that the term 'stalker' no longer means what it used to mean--the pathological ANONYMOUS follower and tab-keeper of another person or persons (A detective who has not been hired and has no real reason to follow someone). The old definition also would say that a 'stalker' often has an imaginary connection with the stalkee.

HOWEVER, common usage of the term, along with the term 'creepy', has come to be used as a defense mechanism for anyone seeking justification for not being attracted socially or physically to someone else.

This term is nearly as overdiagnosed as ADHD is in children. Any women who think an undesirable man might be interested in her will almost always automatically label him a stalker.

Note: Far too many idiots think they're more important than they really are. Real stalkers seek out beautiful, interesting, and often famous members of the attractive gender. 90 percent of the people who use the term couldn't get a real stalker to save their lives.

a person obsessed with another to the point of insanity. I.E. following one everywhere, calling constantly, not following restraining orders, collecting their hair in shower drains

Someone who:
1. Literally follows a person's every move, on Facebook or otherwise.
2. Is way too obsessed with someone to the point of being a creeper.

I did not know what a STALKER is until I become one. A stalker can sit in a car nearby a persons house for hours straight. A STALKER poisons the victim's WLAN ARP table and sneaks into the person's Facebook account and takes notes about the persons friends and comments. A STALKER observes who visit the person and feel enormous jealousy towards them. The stalkers would make quite good private detectives.

Most notorious STALKERS build a shrine for their victim and plaster the victim's photographs on the wall around the shrine. They are the REAL PSYCOPATHS. More mild cases just write definitions into URBANDICTIONARY.

Someone that is obsessed with a person. Watching and noticing every part and piece on your body. A person that craves attention so they stalk you because they want the same attention. A person with great interest and finds everything about you remarkable yet have no idea who you are.

a creepy guy who knows what youre doing at all times and when he dosent hes trying to know. Someone who harrasses, annoys, provokes because of self contempt and jealousy. Is known for doing anything to get a reaction. Will go to any length because hes so f'in sad and has no life whatsoever. Bruised ego loser.
