Definition & Meaning of "reddit warrior"in English

What is the origin of the term "reddit warrior" and how is it used?

"Reddit warrior" is a slang term that emerged in the 2010s with the growth of Reddit and similar online forums. It builds on the older idea of a "keyboard warrior," applying it specifically to Reddit users who are seen as argumentative, self-important, or overly confrontational in comment threads. The term reflects stereotypes about online debate culture, where users aggressively argue, moralize, or posture without real-world stakes. It is used in informal speech and online discourse, often dismissively, to mock perceived performative outrage or obsessive arguing. The term is mildly to moderately derogatory and context-dependent, usually targeting behavior rather than identity.
