1938, Louis Armstrong (and lyrics by Johnny Mercer), Jeepers Creepers
Jeepers creepers, where'd ya get them peepers?
Jeepers creepers, where'd ya get those eyes?
Someone who peeps; a spy.
(dated, slang, derogatory) A private detective.
So you go to see this peeper, this Marlowe. That was your mistake.
A peeping tom.
An animal, such as some frogs, having a shrill, high-pitched call.
(colloquial) A chicken just breaking the shell; a young bird.
