Place it at the end of a short fail sequence, after a build-up sound like Sudden Suspense and just before the reaction settles. Follow it with Wrong Answer Game Show when the mistake is the point, or leave it alone when the failed moment needs no extra comment.

This short Fredrik clip runs for just under three seconds and works as a quick reaction sound, built around that name and the frustrated feeling behind the uploader's FML note. It lands with a flat, fed-up exasperation that suits a small disaster, a failed plan or a moment that goes wrong for no good reason, giving listeners an instant way to share that disappointment without explaining it.
