Place it right after the failed moment in your edit, then follow it with Nelson's Ha-Ha! for a second beat, or lead into it with Wrong Answer Game Show when a quiz guess goes wrong.
About this sound
This is a short spoken taunt, lasting about three seconds, delivered in a confident voice that sounds like it is aimed straight at someone who just missed out. The line is playful and mocking rather than angry, giving it a smug, teasing edge that makes a failed attempt feel even funnier. It works best as a quick verbal jab after a near miss.
