The clip comes from Markiplier's YouTube playthrough of the indie horror game Claytown Horror, where his commentary often becomes more memorable than the scares themselves. A short, quotable complaint about something being moist was lifted from the video and shared as a standalone sound on soundboards and in edits. It sits alongside other horror gaming reactions like the FNAF Jumpscare Scream, but works in the opposite way, using quiet disgust instead of a loud scare. It remains popular because moist is a word many people already find unpleasant.
