Throw out (Where and When the Expired Were Thrown Out)

To throw out usually means "to dispose of, discard, get rid of [trash]," but where the expired are thrown out, the verb throw out has acquired an idiomatic social meaning, namely, "to banish from society [an expired person]." (One who has been banished from society is called a throwout, and the banishment from society is called outthrow.) Such banishment is not punishment for actual offenses, but rather a social health precaution to protect society from the "expired."
