The name is generally considered to mean excessive modesty, and hence unflattering, and is often used as an insult. A person who is considered a prude may have reservations about nudity, participating in romantic or sexual activity, drinking alcohol or consuming other drugs, or participating in mischief. These reservations may stem from shyness or strict moral beliefs. Actions or beliefs that may cause someone to be labeled a prude include advocating or practising abstinence, advocating prohibition, advocating censorship of sexuality or nudity in media, disapproval of being topless in public, avoiding or condemning displays of affection, or exhibiting unusual levels of discomfort with sexuality, alcohol, drugs, or mischief.

Like modesty, one’s perceived prudishness may vary according to who is present.
