Similar to Penis Envy and haterism mostly found in large males with small penis(s). Subjects affected will display a limited personallity usually manifest with phrases from six years of mainstream cinema and other sorts of bland entertainment choices. Males with penis rage will take all aggressions out on others more fortunate not only in life but down stairs.
