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.
The
girl acts as though she had a Tastee Freez dispenser up her
butt. Pretends the thought of having sex has never entered her mind. Yeah, right, and nice
girls shit ice cream.
