"Beep, beep" is onomatopoeia representing a noise, generally of a pair of identical tones (beeps) following one after the other, often generated by a machine or device such as a car horn. It is commonly associated with the Road Runner (commonly interpreted as "meep meep") in Looney Tunes cartoons featuring the speedy-yet-flightless bird and his constant pursuer, Wile E. Coyote. Beep, Beep is the name of a 1952 Warner Bros. cartoon in the Merrie Melodies series.
