The exact origin of this particular splatter clip is unclear, but sounds like this are common across games, meme edits and short-form videos. They are used whenever a creator wants a wet impact that feels nastier than a simple pop or thud. Online, splatter effects stay popular because they work in both horror and comedy, depending on the visual they are paired with. They are often chosen instead of a cleaner pop SFX when the goal is to make a moment feel sticky, gross or exaggerated.
