Wild Magic comes from Dungeons & Dragons, where the Wild Magic sorcerer subclass in the 5th edition Player's Handbook rolls on a table of random magical effects after casting spells. As actual-play streams grew popular, the surge roll became a highlight moment, and many tables replaced a plain d100 roll with a spinning wheel visual. Short wheel-tick sounds like this one spread through soundboards and stream overlays as a way to sell that pause. It stays useful because every surge feels different, so the familiar spin never gets old.
