Place this clip at the very end of a build up, after a sudden suspense sound effect, then follow it with the Nelson Ha Ha sound effect to let someone else get the last laugh on the bad reveal.
About this sound
This clip is Melcochita saying “No lo vean” in Spanish, a just over one second voice line meaning “Don't watch it.” His emphatic delivery makes it feel funny and bluntly dismissive, like a warning that lands as a joke. It comes from Peruvian comedian and singer Pablo Villanueva, whose stage name is Melcochita.
