Facestabbing

The art of applying a slam, inflicting an insult or gossipping on Facebook. The comment is done in such a way that the reader may not even know they, or someone they know, is being Facestabbed. If the reader is fortunate, a post from someone else will connect the dots and the reader will have an "I get it moment" and know that so and so has just been Facestabbed.

I didn't even realize that Laura was facestabbing Angie on Facebook the other day.
