"Rachael Ray" is a slang term describing a woman with artificial, unabashed perkiness, an annoying voice and disproportionate physical attributes that, though unattractive in and of themselves, combine with the other factors in an unholy fashion to evoke the desire to bang her brains out anyway.
Often feeds into latent S&M tendencies. Due to the repulsive nature of having such desires, these inclinations are neither expressed nor confessed, and frequently erupt in fantasies of the oral or anal nature. See also "Mary Hart", "Joy Behar", and "Ann Coulter".
