The exact origin of this sound is not documented. It circulates on user-generated soundboards under the title “del solar Thanks TONY!” with no credited speaker, show or recording attached, and the “del solar” part appears to be an uploader tag rather than a source. Because it is so short and generic, creators have adopted it as a reusable thank-you meme rather than a reference to any specific moment. Its popularity comes entirely from that usefulness: a quick spoken thank-you that fits almost any grateful or sarcastic reaction in short videos, streams and edits.
