An occurrence of an overwhelmingly large penis on a male who is an underachiever in all aspects of life. Said male is unlikely to use his gift except on unworthy (ugly) females. One with a goon cock does not know of their blessing as they have only compared themselves to those on the videos they watch, and feel they are "slightly above average."
Tom may be the poorest, dirtiest and ugliest guy in the entire county, but I hear that lucky son of a bitch has a goon cock!
