The phrase works online because it is familiar from everyday storytelling, where speakers use it to connect one event to the next. In short videos, that familiarity makes it an easy shorthand for anticipation, even when listeners do not recognise a specific clip or speaker. Editors tend to drop it at the end of a setup, letting a single beat of silence or a cut do the rest of the work. Its brevity is part of the appeal, since it can be reused across comedy, reactions and storytime formats without drawing attention to itself.
