A recent question on EL&U about a current hip-hop expression led my research into a meme that is evolving faster than drosophila. This expression and its variants have gone viral on internet videos, and is morphing quickly. Urban Dictionary lists several dozen closely related variations. Of particular interest is how this meme is attaching itself to other "loaded" expressions to spawn combination phrases. In trying to wrap my brain around the complexity of this cultural phenomenon, I imagined trying to draw a sphere-of-influence graph of this meme. Which leads me to my question. Biology has cladistics. Does etymology have something similar? Is there a standard means of diagramming the evolution of a word or phrase, and, if so, what is it called?
