Place it immediately after the fail itself in your edit, then follow it with the sad violin sound button to keep the sequence going, and finish with Nelson's ha-ha sound button if you want the audience to turn on them completely.
About this sound
A very short spoken Portuguese line, 'oh tadinho da puta da Barbie,' delivered as a mocking one-liner in about three seconds. It feels cheekily sympathetic rather than kind, turning a small misfortune into a teasing put-down listeners use for comic effect. The clip was lifted from a recording by the Kesyn & Skelter channel.
