Stalkerizing 

The process of someone following you in and out of internet chat rooms. Or locating you by checking their buddylist every 10 seconds to see where you are.

Micah is stalkerizing me.

Stalkering 

The process of using stalker-like tactics to figure out the mental or emotional state of another person in lieu of just asking them.

The person receiving the attention is being stalkered.

Not to be confused with stalking, in which the person is actually obsessed with someone.

Bob: "I wanted to see if Megan was over her ex, so I logged into her Verizon account to check out how often they still text each other."

Bill: "Wow that's some clever stalkering, what did you find?"

Bob: "They were texting at 3 AM the other night. I'm gonna dump that ho!"

Stalkvertizing 

When you go a website once, and for the next week, everywhere you go you see their banners. That's stalkvertizing.

I looked up a camera on Amazon the other day, and now every website I go to Amazon displays banner ads for that camera all over the page. That's some serious stalkvertizing.
