In human sexuality, kinkiness is any unconventional sexual practices, concepts or fantasies. The term derives from the idea of a "bend" (cf. a "kink") in one's sexual behaviour, to contrast such behaviour with "straight" or "vanilla" sexual mores and proclivities. The term kink has been claimed by some who practice sexual fetishism as a term or synonym for their practices, indicating a range of sexual and sexualistic practices from playful to sexual objectification and certain paraphilias.
