brony

Picture the internet in October 2010: a new cartoon about brightly colored ponies appears, and grown men begin watching it with suspicious enthusiasm. On October 25, users of 4chan reportedly fused bro with pony, producing brony—a word that sounds as if a fraternity had opened a stable. The pony half has an unexpectedly ancient pedigree: English pony traveled through Scots powny and Middle French poulenet, “little foal,” back to Latin pullus, “young animal,” and ultimately the PIE root *pau-, “few” or “little.” That same Latin pullus is related to terms such as pullet, while pony later wandered into meanings like a small drink, a cheating aid, and the “one-trick pony.” The memorable trick is that brony is not simply “bro plus cartoon fan”: it turns an old word for a little horse into a badge of affectionate, unexpectedly adult fandom.
