NPC on TikTok stands for "non-player character". In video games, NPCs are characters that are not controlled by the player and usually populate the fictional world of the game. On TikTok, people are pretending to be NPCs by acting like automated characters with pre-written dialogue, repetitive movements, and catchphrases. During livestreams, viewers send monetary tips to the creator, which appear on the screen as cartoon gifts, and the creator reacts in real-time with a catchphrase depending on what gift appears on the screen. Some creators have made a fortune from this trend. NPC content is a growing trend on TikTok that is amassing millions of views and earning top practitioners thousands of dollars per day.
