Mana Void is the ultimate ability of Anti-Mage in Dota 2, dealing damage based on how much mana the target is missing, and it has long been associated with high level carry play. Arteezy, real name Artour Babaev, became one of the game's most watched streamers and pro players, and this clip comes from a 2015 Oddshot capture of his broadcast. As Oddshot clips spread through forums and soundboards, the short blast became a reusable shorthand for a sudden, mana punished kill in Dota edits.
