The NPC craze is a digital phenomenon that has gained popularity on social media, particularly on TikTok. NPC stands for "non-player character," which refers to characters in video games that are controlled by the computer rather than by a human player. In this trend, TikTok streamers pretend to be NPCs for hours on end, repeating phrases and actions as viewers send them gifts. Some streamers have made a fortune from this trend. While some believe that this is just another passing fad, others speculate that it may have a longer lifespan. The NPC craze has been described as bizarre and wild.
