Villagers are the passive NPC traders in Minecraft, the sandbox game released by Mojang in 2011, known for their large noses, green robes and trade offers paid in emeralds. Their entire language is a loop of pitched hums and grunts, which players have recorded and reused for years in Let's Play videos, animations and memes. Like the Roblox oof, the sound became shorthand online for a game character reacting without speaking. It remains popular because any viewer who has played Minecraft instantly pictures the villager mid-negotiation.
