Outer beauty wrong to desire, no matter where on that person's
Physical attraction should ALWAYS be ignored and reviled. If a man likes the cheerleader or a woman likes the jock, they are either a jerkass are have a life lesson on the way. If a work does not depict Beauty Is Bad than it is in danger of being considered Reality Is Unrealistic. Humans seems to be required to ignore their physical desires and pursue the oily pimple covered nerd over the quarterback with the great hair and flirt with the heavy girl in the corner over the blue eyed red haired cheerleader. Remember, if you are looking for more than a quick fling than you are much more likely to find it arms of the chubby flag girl and the chess club captain than in the arms of the pretty boy actor or the the swimsuit model. Note: This tropes in NOT about the attractiveness of the person, but the attraction TOWARDS that person and how that attraction is regarded by others. If you are looking for tropes about what beauty means see some of the following: Beauty Is Bad, True Beauty Is on the Inside, Beauty Equals Goodness, or Evil Is Sexy.
ExamplesAnime and Manga Naruto - Many fans hate Sakura for this reason when it comes to her infatuation for Sasuke over Naruto. (and sorta Rock Lee) Film Shallow Hal - Built on this trope. Literature Harry Potter - The boys, particularly Ron, that are attracted to Fluer Delacour is treated this way by many of the other girls when she is visiting Hogwarts.
