Markiplier, the YouTube gaming creator Mark Fischbach, became known for his deep voice and theatrical reactions during horror and comedy playthroughs. Short lines from his videos are frequently clipped, remixed and repeated as copypasta across forums, Discord servers and video edits. This who's coming clip followed that pattern, spreading as a reusable reaction rather than as a full scene, with fans quoting the phrasing in comments and captions whenever someone was about to arrive. Its longevity comes from how recognisable his delivery is even out of context.
