For what its worth, from my observation, the late 1980s, early 1990s dance "Da Butt" was danced the same or very similarly to the Black Bottom and not the Funky Butt-meaning the women certainly did not "raise their dresses or skirts to show their petticoats" but did the wining, grinding Black Bottom moves as described above. While "doin the Butt" the men would sometimes slap their female partner's behind or might hold it as mentioned above.

Another African American dance from the 1990s (or was it the 1980s?) in this same family was The Bump. The Bump was performed by bumping your hip to your partner's hip, and is a true descendant of the old dance Gottschild wrote about, "The Fanny Bump".

Also, Gottschild was right that the African American social dances* keep recycling African dances and older African American dances. One of the newer Black R&B dances is Do The Stanky Leg. Even the name of that dance's its name shows its lineage to the "Funky Butt"-"stank" means "stink" and so does "funky": And when the singers say "Hit that boody do", you can really see the continuation of the Black Bottom dance.

*The Caribbean butt wining dances also reflect certain African dance movements.
