The act of abusing someone's Facebook account on a computer where they have left themselves logged in. Usually results in a change of status proclaiming their sudden change in sexuality, as well as numerous wall posts to friends containing bizzare messages.
I left my Facebook account signed in on Jacob's computer last night and he completely Faceraped me!
another term lazy punkish scene kids use for their make up. originated randomly one day from the mouth of a girl who did not want to sound too girly. Most people may find it rather disgusting, but it's all in the attitude.
