A nonswimmer is a person who is usually referred to as a soccer player because they do not swim but play soccer instead. Nonswimmers believe that even without practice and time and effort they could race a swimmer and win. A nonswimmer also thinks they are stronger than swimmers, abd therefore as a joke swimmers take their side. A swimmer will never date a nonswimmer until they have been proven worthy of the title swimmer or are an Olympian.
