Chewbacca first appeared in Star Wars in 1977 as Han Solo's loyal Wookiee co-pilot, and his distinctive roar became one of the saga's most recognisable sounds across the films that followed. Sound designer Ben Burtt built the voice from layered animal recordings, giving it a growling, expressive quality that felt both alien and emotional. As Star Wars clips circulated online, the roar was lifted onto soundboards and into memes, where it now works as a shorthand for excitement, loyalty, and playful chaos.
