The Douche Horn is that cliche air horn sound that is only played by people who don't realize it's not 2009 anymore, and/or still think it's cool.
It serves as a "musical" stinger or stab when someone doesn't can't think of something clever and is happy to copy something that may have been interesting a long time ago. For example, if you search YouTube for "DJ Airhorn Sound Effect" you'll find a sample which demonstrates the sound and which has been around since 2016.....and it's not the first.
It's the audio equivalent of "that's what I'm talking about," "yeah, baby," "that's the ticket," and the Borat "High Five-a."
Simply put...only a douche would play that sound and think it's a good idea after 2014.
That DJ blows. He keeps playing the Douche Horn unironically over the music.
