Place this laugh at the end of a short edit, right after the moment your character's plan succeeds. Follow it with the Darth Vader Nooo sound button for the victim's reaction, or precede it with a fail sound meme button to set up the mockery.
About this sound
This clip is Lord Farquaad laughing for about 15 seconds, a sustained laugh in the character's voice. It feels amused and mocking, like a villain enjoying a moment at someone else's expense, which makes the laugh read as smug rather than friendly or surprised.
