Put this clip right on the reaction beat, after the setup line and before your response shot. Follow it with the Roblox Oof for a second fail hit, or precede it with the FNAF Jumpscare Scream when you want the gag to escalate fast.

This is an extremely short distorted Sans blip, lasting under a second, with the familiar low text sound pushed into harsh, peaking distortion. It feels abrupt, funny and a little obnoxious, like a punchline that interrupts before anyone can react. The character comes from Undertale, where that blip marks Sans talking.
