Defacebooking is sabotage of a friend’s Facebook ‘Wall’. Typical examples of defacebooking include outing the friend as a pedophile, a truant, a stealer of office supplies, a backstabber of BFFs, or a closet Mormon.
I had to un-friend Jeremy for defacebooking me! He ratted me out on my Wall for trying to poach Chase’s not quite-eighteen year old sister at Chase's party. Jeremy waited til I had just started my shift, and when I logged back on my Wall was like totally covered in flames.

Get the defacebooking mug.
1. the act of removing a facebook account
2. the act of removing someones face with a book
(1) I think its finally time to delete my account and go through a defacebooking.

(2) This crime scene appears to have been a defacebooking... I can tell by the fact that there's a face on the floor and a bloody book nearby.

To remove a stalker, crush you didnt know wasn't just a friend because everytime your in a picture with a guy or girl they get jealous ?
I was at a party with a bunch of people and I just happened to be with a cute guy in a picture and was tagged and it posted to my profile ... now a guy that was just a friend ... I thought is all jealous and pissed off and going to fight for me ...what the fuck we went to the movies once? maybe lunch as friends. You are now "Defacebook crush"
