The line belongs to Witch Doctor, the troll voodoo hero in Dota 2, and is used in game as a response when a deny occurs. Players and streamers lifted the brief, panicked refusal out of matches because its repeated no works as a universal reaction to something being taken away or shut down. Shared through Dota highlight reels, short videos and soundboards, it survived beyond any single match as a compact way to say no, loudly and repeatedly, to a bad play.
