The line comes from The Witcher 3: Wild Hunt and its Blood and Wine expansion from 2016, set in the wine making duchy of Toussaint. Its knights errant speak in exaggerated chivalric oaths and compete in tourneys, making the cry a perfect summary of their proud culture. Clips of the delivery spread through gaming forums and soundboards because the formal phrasing works out of context, turning everyday wins, charges and entrances into parodies of knightly honor that Witcher fans instantly recognize.
