What is Flutterrap?
Flutterrap refers to a collection of stories about the cold ass ponies from MLP spitting dope shit on a microphone and bucking it old school.
While the title implies that it is Fluttershy trying to get that scrappa with a mic, other ponies may follow in her hoofsteps and ball as hard as they can.
There are many different versions of Flutterrap, but mostly they are lighthearted stories about the OG ponies spitting game, smoking trees, and hustlin' every day.
