Sniffing in disdain - another pre-verbal narrative pattern

The "sniff" is a sharp attack, followed by diminuendo. I wonder if this is the precursor for laughter?

One barely notices this pattern, but listen for it when you pass someone in the hallway. Some people cannot help but let you know they don't think much of you. Like yawning, it reveals an insecurity.
Update:  I was thinking how the sniff, which is an inward breath, cannot be the same as a laugh which is an outward breath. Also thinking how the sniff could not be associated with any words as no one speaks while inhaling. But actually the Parisians say "oui" on an intake.
Update: This may or may not be related to howParisians are famous for their disdain.
