AAVE is the best damn thing to happen to the English language in our era. It makes sense that broader (aka white) culture likes to adopt it.
But as @thetrudz and many others deftly point out, the did between “adoption” and “appropriation” is whether originators are reviled for it
i.e. treating white folks as modern & hip for using language flourishes we treat as “disqualifying ghettoness” in, say, a PoC job applicant
It’s the double standard that really helps the complexities of “appropriation” click for me & why saying it’s just adoption misses the point
In conclusion http://www.alternet.org/culture/cultural-appropriation-pho-lionel-shriver-jamie-oliver-marc-jacobs should prolly be tattooed on every social media manager who wedged “on fleek” into a product tweet
