The exact origin of this dono clip is not documented, but its use online follows the familiar pattern of short streamer alert sounds that get lifted into edits and soundboards. A three-second voice line is easy to recognise, loop, and drop into unrelated scenes, so the peanut butter wording becomes an in-joke for anyone who has heard it as a donation cue. It stays popular because it needs no setup and still feels personal, like an inside reward for the audience.
