Fralker

A person who friends you on Facebook, then stalks you via your status updates. Their eventual goal is to meet you in person and freak you out by the vast amount of knowledge they have about you.

Jay: Hello, Rosh. Did you just come from hot yoga?

Rosh: Um, do I know you?

Rosh: Dude I met my fralker today. Creeper!

Kristin: I told you not to friend people you don't know.
