When a desperate girl or woman (typically overweight) lights up your Facebook with comments that make it appear as if the two of you are dating. This usually happens whenever your relational status is set to single (and in some cases when you don’t have a relational status set). By doing this, she effectively sends a nonverbal signal to potential mates that you are already dating, but haven’t made it “official” yet.
Desperado’s comment on wall: "Hey thanks so much for talking with me last night! I can’t wait to see you next weekend!"
The poor male’s mental response: "What the hell? Since when does ‘nothin’ as a response to ‘whats up?’ on Facebook chat constitute as talking? Next weekend? What the fu- oooohh, that bitch is trying to Facebook cock block!"
