a combination of the words "stalk" and "awkward", used to describe a person that is strangely and inexplicably informed/knowledgeable of another person's activities; also used to describe situations in which you could conclude that you were being followed/watched but probably not, and so it is just awkward.
"Oh man, how did he know that I went to Richmond yesterday? I haven't seen him in three months! That is so stalkward."
"This is getting a little stalkward. This is the fourth day in a row that I've bumped into you."
"Hey! Isn't that the guy who was siting behind us on the bus yesterday?"
"Ah, stalkward."
or
"Hey, don't I know you from somewhere?"
"No, I don't think so"
"No I do! Oh I know, from social networking site.....oh..stalkward."
Awkward situation when it become obvious to someone else you have been stalking them on social media.
It was totally stalkward when I asked the new girl at work about the party she went to this weekend that I only knew about because I stalked her on facebook.
