NicheTok, or TikTok Niche Communities, refers to the platform's algorithmically driven ecosystem where users find themselves in highly specific interest groups. These 'corners' of the internet range from aesthetic movements like Cottagecore to abstract styles like Corecore or Hopecore. The meme typically highlights the experience of falling down a rabbit hole into a world that feels incredibly personalized yet bizarrely specific. It captures the feeling of finding 'your people' or just being confused by a strange trend that appeared on your For You Page. This template allows users to label the specific and often absurd communities they encounter while scrolling late at night.
