A common delusion afflicting the self-styled "nice
girl" (who may be either male or
female), which consists of the mistaken belief that he/she is soooo superior to the "great unwashed" masses that he/she is excused from the indignity of being subject to the same natural bodily functions as the rest of us. One specific sense of the word denotes sexual frigidity -- i.
e., "nice
girls" don't have orgasms; they only submit to sexual intercourse in order to fulfill their duty to God and Country.
