The line comes from the I'm Sorry carving in Dark Souls, the 2011 action role-playing game by FromSoftware. Carvings are small wooden items players can drop to play a spoken phrase for others in multiplayer, letting them communicate without voice chat. Clips of the pleading apology later spread through gameplay videos, streams and soundboards, where its exaggerated regret made it perfect for fails and accidental betrayals. It remains popular because Dark Souls is known for punishing mistakes, so a frantic apology fits almost any in-game disaster.
