The ahooga takes its name from the sound made by early klaxon horns fitted to automobiles in the early 1900s, including cars of the Model T era. As those horns disappeared from roads, cartoons and comedy films kept the noise alive as shorthand for vintage vehicles and exaggerated surprise. The spelling ahooga became the common way to write the sound online, helping it spread as a meme sound effect on soundboards and in short videos, where its old fashioned character instantly sets a comedic tone.
