De-facebook 

The act of removing some person who at one point was a friend with you on The Facebook, because of spite and hate toward the De-facebooked individual. It could be because that person possesses beat, whack, shitty, stupid, or just aggravating qualities. For those who are extremely bitter/hateful multiple correlated or uncorrelated De-facebookings may occur simultaneously.

Those who have been De-facebooked are also no longer considered friends in life outside of The Facebook.

Person One: You that bitch screwed me over hard as hell by saying she would come to our party and didn't show up.
Person Two: Dude the last girl that did that to me got De-facebooked hard as hell. Plus I De-facebooked her friend too just because she was fat.
