R2D2 is the beeping astromech droid from Star Wars, first introduced in the 1977 film and instantly recognisable for communicating entirely through electronic chirps and whistles instead of words. This clip is not taken from a film soundtrack; it is a human impression by Mose, recreating that droid language with his voice for a soundboard audience. Impressions like this stay popular because they are instantly readable, work without subtitles, and let creators add a Star Wars reference to edits, streams and reaction videos without using copyrighted movie audio.
