This's a sound effect/vocal effect created by sound designer Jeff Hutchins at Hacienda Post, debuting in the SpongeBob Squarepants episode "Something Smells". The sound is, according to Jeff, "a slow close up exhale", with an "end grizzle bits out of a can of shaving cream as it dies", of the 6 sound effects involved. Following the exhale is what sounds like someone gagging consistently.
- Chowder (heard in “Burple Nurples”)
- The Marvelous Misadventures of Flapjack (heard once in "Cammie Island")
- Out of Jimmy's Head (Heard once in "The Mascot")
- SpongeBob SquarePants (Debuted in "Something Smells"; heard mostly in later episodes)
- Tom and Jerry: The Fast and the Furry (2005) (Heard as Tom unleashes fish smell from his car on Jerry.)
