The exact origin of this clip is not documented, so it circulates online mainly by its catchphrase rather than by a named show or creator. Short phrase clips like this spread on soundboards and in short form video because they are easy to search, easy to drop into edits and instantly understood out of context. Everytime u tell me is the common shortened spelling used in titles and searches, while the split every time version matches how people type the line. Its appeal stays in that everyday repetition it calls out.
