floss and ghetto

[Luanne von Schneidemesser]

Two queries.  Someone asked about the meaning of ghetto, as in "that was
ghetto."  It must be fairly new; it's not in the HDAS.  My son uses it but
isn't a great definer so wasn't really helpful.  What's its earliest date?

Then I received the following:

I recently attended an Afrocentric poetry reading in which two of the poets
used the word "floss" in their poems.
It seemed, from the context of both poems, to be a pejorative reference to
an undesirable trait/behavior in African Americans. In one poem the subject
was a woman, and the other, a male "type". I think they both used the term
as a verb.
I do not have copies of the poems, or access to the poets--who are not
published.
Thanking you in advance for any suggestions you send me for tracking down
the meaning of this word.

Any help?  TIA.
