This is an old use and still use for this catch phrase to tell someone see you. and the answer for it after while, crocodile, alligator and crocodile were brought for the sake of rhyme.

A cryptocurrency of little to no value, usually a late-comer to the Bitcoin craze, a copycat cryptocurrency.

A silly way of saying “goodbye,” when you or someone else is leaving. It commands a response... “After while, crocodile.”

Originating in the 1950s, the correct response to “See you later, alligator!” is “After while, crocodile!” It is NOT “In a while, crocodile,” or even “After a while, crocodile.” As with most phrases and expressions, accuracy often gets lost through the years, like a giant game of telephone, so nowadays you will hear it said all three ways, but there is an original, correct way. “AFTER WHILE, crocodile!” :)

*Listen to the song, “See You Later, Alligator,” by Bill Haley and the Comets, for reference.
