When did hooters start to mean breasts?

The term "hooters" as a slang reference for breasts gained popularity in the 1960s and 1970s, particularly in American culture. It was likely influenced by the playful and informal nature of the Word, which also evokes the sound of an owl's hoot, often associated with playful or risqué connotations. The term became more widely recognized with the establishment of Hooters, the restaurant chain known for its waitstaff and marketing that emphasizes this association.
