disco smile 

The Disco Smile occurs when someone cranks the BASS and TREBLE way up on their stereo system's equalizer, leaving the mid range very low. On a graphic equalizer, this curve will look like a mouth smiling.

You have now achieved the disco smile. Good job, I hope you didn't *really* want to hear everything that song had to offer.

Lauren: Hey Chris, turn on your car stereo!

Chris: Okay! *click*

Lauren: ARG! Why are my ears bleeding, and I still can't even tell what song it is? Oh, that's right, you're a fan of the disco smile.

Chris: Guilty as charged.

Silent Disco 

The act of masturbation. It is referenced by the noise one makes while in the act.

Eddie : "Where's Petey been?'

Silent Disco 

This term was originally used to name an event in which a group of people all rock out to the same song playing on headphones. However, onlookers cannot hear the song in the headphones and therefore, the group looks ridiculous. While participating in a silent disco, if you turn off/take off your headphones, you can hear everyone messing up the words to that particular song. Therefore, this phrase NOW refers to someone completely messing up the words to a song, but are convinced that they know them, and therefore, persevere.

Joan: "R-E-S-P-E-C-T camelbacks in PNC."
Rick: "Shit, you totally just Silent Disco-ed that song."
