Acostic 

Irreverent , nasty , disrespectful, selfish, unkind, dangerously lacking in situational awareness. One who puts forth a false narrative to make themselves appear relevant. Willing to put others in harm's way to support their selfish agenda.

Acousticophilia 

Acousticophilia is defined as being sexually aroused by any auditory stimulus (including music, songs, poetry, verbal abuse, speaking in a particular foreign language, screaming, panting, moaning, groaning, and heavy breathing). The key to defining it as acousticophilia appears to be that the stimulus itself is not necessarily sexualized.

Willow found that when they were masturbating, playing the sound of someone laughing always made them orgasm. They found the same with certain key changes in music, harmonies, specific YouTube videos and bird calls. Willow has acousticophilia.

Douchebag Acoustic 

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

Anal Acoustics

Like a guitar, anal acoustics is caused by a loud sound erupting from deep within, forcing the sound out of the nearest exit, which then causes your body to perform anal acoustics. (results may vary.)

Another word for Fart.

Epic Dude #1: Dude! Donny stinks really bad!
Epic Dude #2: Ya, he's rockin' out some anal acoustics man!
