Top Definition
A disease in which a teenager regresses in a fit of narcissism, self-centeredness, and egocentrism, refusing to be accountable to own behavior, projecting anger, rage, and immaturity throughout the world, with a sprinkling of ass-holeishness.
A person with assholeitis may display: Screaming in parents' face, in a high pitched, screeching, nonsensical grandiose way, in an attempt to be re-breastfed. A person with assholeitis will also display pervasive denial. (Seek attention from perturbed, tired, teenage peers.)
