Place it immediately after Dry Fart in the edit, so the rebuke answers the joke instead of starting it. If you want one more beat, put Fart Echo before it as the offending sound, then let this clip close the gag and move on.
About this sound
This is a short Spanish voice line, lasting just under six seconds, in which a speaker firmly tells everyone to leave flatulence aside. The delivery is blunt and exasperated, turning a crude subject into an awkward scolding that feels funnier because it sounds so serious. It works as a deadpan rebuke to a joke that has gone too far.
