The origin of Thaaftrpartie is not documented in the information available for this listing, and no source work, performer or year can be confirmed from the title alone. The listing gives only a short duration and a user-generated name, which is common for clips that circulate on soundboards without accompanying credits. In that setting, a clip is usually kept because it is short enough to reuse, easy to place in an edit, and recognisable to people who have heard the same button before. Its continued use depends on reuse in memes, streams and edits rather than on a documented release.
