Phil Leotardo is a fictional mobster on HBO's The Sopranos, played by Frank Vincent and introduced in season five in 2004 as the volatile underboss of the Lupertazzi crime family. The short 'turn that off' line captures his famously short fuse, and the clip has circulated on soundboards and meme pages as a reaction for killing unwanted audio. It stays popular because the demand is instantly understandable with no context needed: one gruff sentence from a mob boss ends any noise.
