Place it at the end of a win or reveal sequence, after the Game Show Correct Answer sting confirms the result and before the Yeah Reaction Sound answers the crowd, so the hundred becomes the final beat of the celebration.
About this sound
This six-second clip from asdfmovie 13 is a fast high-five gag built around a crisp slap and a deadpan cartoon voice that lands on the word hundred. It feels silly and triumphant at once, like celebrating a deliberately dumb win, and the sudden ending makes the joke land harder. It comes from TomSka's long-running asdfmovie sketch series.
