A portmanteau adjective describing something that is both hateful and pathetic - obviously a word that our current social environment needs desperately. It was coined, so far as I know, by blogger Andrew Sullivan, used to describe such things as a 45-year old clip of Barry McGuire singing "Eve of Destruction" with a notable grimace on Shindig, in tight white jeans with a moody junkyard stage set and interpretive "dancing" behind him. Obviously also useful in summarizing the Glenn Beck vibe.
Sarah Palin's attempts at political analysis and debate aim so low and miss so badly that they are merely hathetic.
Derogatory epithet applied to folks (generally middle-aged white males) who adhere to the Old True Faith: that guitar-shredding long haired heroes (think Clapton, Page or Billy Crudup in "Almost Famous") are the true gods of music, and that the early 70's were a golden age for popular culture. Used in political arguments by those who seek to elevate the cultural impact of hip hop or mope-rock as viable alternatives, or even progress. Rockists venerate technique and craft over novelty and youth.
Those turkeys at Rolling Stone are such old rockist fossils, they don't see that 50 Cent is a true artist and Tupac more important than the Beatles
