Get on with it is a plainspoken urging phrase that has long been used in everyday speech to tell someone to stop delaying. As a short soundboard clip, it circulates as a reaction sound rather than as a quote tied to one famous scene, which makes it easy to reuse across unrelated videos. Its appeal is its bluntness: in just over a second it supplies the voice of an impatient audience, so creators use it to punctuate procrastination, dithering, and drawn-out setups without needing any extra context.
