Swept along by events, we have not had time to sketch in the comic race of courtiers who pullulate at the court of Parma and passed droll comments on the events we have been recounting.
-- Stendhal, John Sturrock, The charterhouse of Parma
I do not want to describe it; a chaos of heterogeneous words, the body of a tiger or a bull in which teeth, organs and heads monstrously pullulate in mutual conjunction and hatred can (perhaps) be approximate images.
-- Jorge Luis Borges, Donald A. Yates, James East Irby, Labyrinths: selected stories & other writings
Pullulate derives from the Latin pullulatus, "to grow or sprout," and relates to the Latin noun pullus, "a young animal."
