No, not the plural form of
patio (yuk, yuk, yuk), but
patois itself. A patois is a mish-mash of two or more languages with
street slang evolution thrown in for fun.
Creole is an example of a
patois. Various regional sub-dialects of Chinese are another
example. Consider that
Mandarin Chinese is the most fluently-spoken
language in the
world, but within it, there are tens, if not hundreds of regional sub-dialects(patois). Fascinating, man.
