Place it right after the fake threat lands, then follow it with a Bruh before the edit cuts away. For a longer chain, open with Goofy Ahh Sounds and let this clip answer the buildup at the end.
About this sound
This six-second spoken clip delivers the line "oh shiver me timbers" in a big, stagey voice, as if the speaker is recoiling from a sudden fright. It feels funny because the alarm sounds far bigger than the threat it answers, turning a mild scare into mock panic. That exaggerated fear makes it work as sarcastic shock, playful intimidation, or a knowing reaction to someone trying to seem menacing.
