see you later

Goodbye. This somewhat loose phrase—one need not necessarily intend to see a person in the future—dates from the latter part of the nineteenth century and has been widely adopted as a farewell. Children play on it with the rhyming See you later, alligator, sometimes adding on in a while, crocodile. These rhyming plays were popularized in a song, “See You Later, Alligator," by R. C. Guidry, sung in the film Rock around the Clock (1956). The telephone equivalent, used to end a conversation, is Talk to you later, a more recent phrase that is similarly widespread.
