One of the problems with the idea that “thicc” has a meaning different from “thick” is that one also observes “fucc” for “fuck”, “succ” for “suck”, &c.
The recent slangy of “thick” emerged within the black community as a reference to
plumpness, to
overweight, and to
obesity by those who found such
desirable in women. After that, we got a variation on
the Problem of the Chinese Tattoo, in which many outside a linguistic group ineptly attempt to adopt its vocabulary, in an effort to be seen as part of an in-group. So “thick” and “thicc” are now used by
obliviously awkward White and Asian guys to mean
desirable.
Maybe someday, by a similar process, “zhīfáng”, respelled as “sheefong”, will be English slang meaning
beautiful, but educated people will think first of
fatness.
