First things first. It must be noted that Young Thug was not wearing a dress when the crowd sang line for like with him from his verse on T.I.'s “If ain't about the money.” from at Newport January 23rd.
If you're not familiar with Young Thug; he is from Atlanta and often referenced by the fact he is a Blood that boasts Rich Gang Affiliations as well as your usual Waka/Gucci overlaps.
He has a stream of consciousness, sing-songy cadence that is post-Lil Wayne/Future in terms skating with melody and sometimes not discernible.
Rappers like Thug, Rich Homie Quan and Migos are developing a nuanced version of Weezy.
Why do I mention him wearing a dress? Because dudes who rock the same circuit as Kevin Gates and Plies with the word Thug in their name don't usually wear dresses. Sort of.
Young Thug does.
I could go through several theories on why gender fluidity exists in Blood Branded rappers compared to similar organizations. My guess it boils down to the people involved, molly commerce, prison culture, New Orleans Sissy Bounce and perhaps just the entertainment industry.
