The clip is tagged for Baldi's Basics, the indie horror game built around a strict teacher, a school and a series of maths problems that quickly turn into a chase. Sounds from that game spread widely through gameplay videos, edits and short-form memes, where a single harsh noise could stand in for punishment or failure. This loud slap fits that pattern perfectly, so creators keep reusing it whenever a character deserves an instant, exaggerated consequence, especially in school-themed jokes and gaming compilations.
