the.com/patois

means A regional or informal dialect spoken by a particular community, often distinct from the 'standard' language and looked down on by those who set the standard.

from From French patois, meaning rough or clumsy speech, probably related to patte (paw) — as if to say the common people were speaking with their paws instead of their tongues, pawing at language rather than properly handling it. A word born sneering, now often worn with pride by the people it once insulted.
