Happy Wheels is a side-scrolling ragdoll game released in 2010 by indie developer Fancy Force, built around absurd vehicles and gory, physics-driven crashes. The game became a YouTube staple in the early 2010s, when Let's Players like PewDiePie turned its painful wipeouts into comedy gold. Short vocal reactions from its characters, including tiny grunts and winces, got ripped from gameplay and shared on soundboards, where creators reuse them to score their own fail moments and meme edits.
