Facebook Rape occurs when an individual leaves Facebook signed in and open to interference from a housemate, work collegue or other third party scumbag with nothing better to do.
Such rape often results in personal details and profile pictures being changed to hillarious, often false but in some cases, true information. High levels of damage occur when the third party has long periods of time in which to Rape your Facebook.
