From the tweets I've seen posted here it looks like girls lashing back for getting teased when they were in school. But that goes both ways, I went to elementary school with a few liberian girls who couldn't speak a lick of english (they spoke french). Fast forward to high school you wouldn't be able to tell the difference between them and the American born girls, from style of dress all the way down to dialect/slang, and now they back reppin Africa hard..are they "appropriating" two cultures at once?
This is pretty much what I was alluding to, story is very common/familiar.
