oroboros commented on the word fat tail
In essence, as related to small-world network theory, the more connections a network node has, the fewer in number are such nodes. A graphing displays the classic "power law" pattern where the y axis = # of connections vs. the x axis = # of nodes with y connections generates a curve showing a rather steep fall-off--hence, the "fat tail".
