The genre of music played by guys who never learned to actually play guitar, usually consisting of three chords and with lyrics about how sensitive they are and how much they love someone they just met (i.e. Justin Bieber)
Man 1: How the hell does he get all the chicks, he's terrible.
Man 2: It's because he plays a douchebag acoustic.

Man 1: Hey, I just learned how to play "Hey there Delilah"
Man 2: Congratulations, you've mastered the douchebag acoustic, now get out of my house, we can no longer be friends

Get the Douchebag Acoustic mug.
when a guy decides to be a douchebag under the belief that most people agree with his actions, only to realize that he has no support or back up in the entire world.
You read that thing in Forbes, about that acoustic douchebag being mocked on Facebook, after whining about getting booted from a bar in Seattle for refusing to take off his Google Glass?
