The story
First known use, by meaning
- from 2020 A Twitch community characterized by chatters reacting to events using W and L in text, instead of using traditional (or custom, browser-extension-provided) emotes. Associated with relatively more mainstreamized, hip, recent-influx Internet culture and black culture, in contrast to the poggers community which is associated with more traditional gaming culture and nicher, shibbolethic image reaction-based humor.
