The Etymology of 'Shorty' in Hip hop

Love all the research and effort that went into this. I like most of the visuals except the grayscale hover near the top awkwardly that wiggles the text.

This is an aside, but I'm curious about the quoted lyric near the bottom:

"... Bounce that ass up & down; make a n* * * * want it. Roll that ass round & round like a motherfucking wheel ..."

Does anyone else find that bit of censorship a bit out of place, especially given the content of the lyric and the fact that it's a quotation?
