In the seminal Anthropological work, Homo Ludens, Johan Huizinga explores the ways in which play is ingrained within human culture. One of the key terms Huizinga describes is that of the “magic circle”. Coined originally from the Mahābhārata (57), Huizinga uses the term to signify the space wherein cultural norms and expectations are altered. Spaces where the magic circle takes effect includes things such as rituals like the potlatch (58‐61), but Huizinga mostly focuses on spaces of play, such at the dice game of the Mahābhārata or the tests of virtue and strength which many cultures have (60‐70). Therefore, one can view behavior such as griefing, as an attempt to recast the magic circle within a play space. Simply put, griefers can be seen as creating a new set of rules by which to play.
