/noun/ pertaining to the phenomena of projection seen in online media where individuals feel the grandiose right to deface others psychic space through electronic mediums such as walls of Facebook. This stems from magical beliefs about one’s special ability to perceive the world and reality. i-ego- graffiti often follows logic on topics such as politics, sports, relationships, and/or religion but is also notable for the individual’s inability to differentiate the manifest content from the latent material (i.e. inferiority, anger, self-doubt, etc.). i-ego-graffiti is a form of sublimation and a primary defense mechanism. i-ego-graffiti artists tend to have little awareness of their motivation.
