Markiplier, real name Mark Fischbach, built a huge following on YouTube with horror and comedy gameplay videos where his exaggerated reactions became part of the appeal. Clips of his laughter have been pulled from streams and Let's Plays for years and shared as standalone reaction audio across meme edits, compilations, and soundboards. This nearly 12 second hysterical clip is a longer cut than most short laughs, letting editors use the slow build-up, and it remains popular because his laugh alone signals that something ridiculous just happened, even without seeing the original video.
