The meep meep belongs to the Road Runner, the famously fast bird from the Looney Tunes cartoons who constantly outran Wile E. Coyote. The character first appeared in the late 1940s, and the simple two-note call became his trademark through decades of television reruns and home video. As short-form video and meme editing grew, the clip was lifted from the cartoons and shared on soundboards as a ready-made punchline for speed. It endures because it needs no context: two beeps alone tell an audience that someone is already gone.
