Often caused by (a) the friend counter or (b) the relationship status. This is the act of deleting ones facebook page.

Can often be depicted as a sad moment where someone finds your action a moment too late and attempts to stop you in slow motion

Dear Facebook, I cannot live like this anymore. My friends are non existant. Facebookacide is the only way out. Goodbye

Facebookucide 

When anything on Facebook makes you so depressed, i.e. seeing your ex-boyfriend's profile, or realizing you have 600 friends and you're alone on Friday night, that you delete yourself.

Neil: Hey, where is Zee's profile?

Christina: Oh, she misses me and seeing my posts made her depressed. She committed Facebookucide.

Neil: Wooord. Dang. She will be missed.
