I did a Google search for "editing techniques film repeat cut".
Top result-

Just happens to be that my guess at a good search term, "Repeat Cut" is the correct term,
Copy/paste- "A visual tool of emphasis, in which the same action, line, or brief exchange is shown more than once in immediate repetition. Often, different angles or takes are used. Sometimes called a "stuttercut" or "triple take" (not to be confused with Double Take)."
