Place this laugh right after a quiet build and before your payoff hit, then follow it with the FNAF Jumpscare Scream for a full horror sequence, or swap that second hit for a Roblox Oof Sound when you want the scare to collapse into comedy instead.
About this sound
This is a short laugh from the Sonic.EXE 2011X character, lasting just under three seconds and delivered in a taunting, villain-style voice. It feels sharp, smug and unsettling, flipping a normal moment into something sinister in an instant. It comes from Sonic.EXE horror fangame and creepypasta fan content centred on the 2011X version.
