The "Diablo 3 ︵ /(.□. \）" emote and "Error 37" emote are references to the launch of the video game Diablo III in 2012, which experienced widespread server issues that prevented players from accessing the game. The "Diablo 3 ︵ /(.□. \）" emote depicts a frustrated player throwing their hands up in the air, while the "Error 37" emote refers to the error message that appeared when players attempted to log in to the game during the server issues. Both emotes have since become popular memes used to express frustration or disappointment with technology or online services.
