I've not read too many of the discussions about this particular xkcd, but none of the ones that I've read have mentioned the name of the particular strip or the tooltip/popup text.

The name of that strip is "Creepy".

The tooltip/popup reads "And I even got out my adorable new netbook!"

FWIW, I read it as irony. He's overthinking his simualtion of the encounter and she wants him to talk to her. And that's it.
