Whistle is constantly mocked by a South Korean girl group.
 In prehistoric Egypt, small shells were used as whistles
 It has been used playfully for people acting in an energetic fashion (Canadian singer Nelly Furtado's "Promiscuous Girl") or as a way of unifying women of all ages on the basis of their once having been girls (American country singer Martina McBride's "This One's for the Girls")
