Anytime someone uses the word "Creeper" it quickly identifies the person as a Millenial. It sounds passive-aggressive.

The word is "Stalker" kids. A creeper is someone who creeps around at night.

A creeper is someone you suspect of being a stalker.

No, really; that's pretty much it. Someone who calls you creepy is expressing a sincere worry that you won't take no for an answer. No more, no less.

So, the term for someone who behaves in a socially inappropriate and over-reaching way, but isn't literally stalking anyone is.... ?

[pekk]

Socially awkward? Unattractive?

[CyberDroiD]

It's called stalking.

No. Stalking is a specific thing (for one, it has a specific subject) that is not what we're talking about here (generic behavior, amongst other differences). http://en.wikipedia.org/wiki/Stalking

The blogger in question graduated Harvard Law in 1994, so it's pretty unlikely that he's a "Millenial".
